Check prerequisite multiplication understanding while building intuition for the game's core mechanic. Mix verbal reasoning with spatial sense to surface both conceptual understanding and physical intuition for equal groups.
Multiply whole numbers
- Interpret products of whole numbers as the total number of objects in equal groups. (3.OA.A.1)
- Multiply within 100. (3.OA.C.7)
Before You Play
Show me with your hands: what does "3 groups of 4" look like? How is that different from "3 plus 4"?
Watch for: Students who hold up four fingers three separate times show multiplicative thinking through gesture. Those who count to 7 on their fingers are still thinking additively and may struggle with "hops of" language until this physical distinction clicks.
Listen for: Students saying "three times you have four things" or "four items in each of three groups." If they describe it in additive terms ("four plus four plus four"), ask them to show it with their hands again—the physical separation of groups often clarifies what words don't.
If you multiply 5 × 4, do you get the same answer as 4 × 5? Show me with your fingers how both work.
Watch for: Students who physically demonstrate both interpretations—five groups of four versus four groups of five—show deeper understanding than those who just state "they're both 20." The hand gestures make commutativity concrete: the grouping structure changes but the total stays constant.
Listen for: Students who immediately know the products are equal versus those who need to calculate both. Second-graders typically need to verify; third-graders developing fluency start recognizing equivalence automatically.
Put your finger on the start square. Now move it to where you'd be after 12 spaces. Try 24 spaces.
Watch for: How students navigate—finger-tracing path square by square, jumping by 10s using the numbered landmarks, or directly pointing to the destination. Efficient navigators will have an advantage during gameplay because they can visualize landing positions before calculating.
Listen for: Students recognizing "24 is double 12" or using multiplication to verify position ("that's like two moves of 12"). This spatial-numerical connection is exactly what the game reinforces.
Setup Tip:
Position the board where all players can reach it comfortably. Students need to physically move pieces and point during strategy discussions—cramped positioning kills this. If using Hopper Helper, place it where everyone can see the screen and reach to trace the arcs.
During Gameplay
Focus on strategic decision-making and conceptual understanding as students encounter multiplication in game context. Use the board as a spatial tool when helpful, but prioritize questions about reasoning and mathematical relationships.
Rolling and Interpreting Dice
You rolled a 3 and a 6. What are the two ways you could interpret this roll? Which one do you want to use and why?
Listen for: Students articulating both options—"3 hops of 6" and "6 hops of 3"—and recognizing they yield the same total. Strategic reasoning like "I want bigger hops" or "I want to land on that green square" integrates calculation with spatial planning.
Watch for: Students who automatically choose one interpretation without considering alternatives. Prompt: "What if you read it the other way?" This reinforces that commutativity offers strategic choice, not just equivalence.
Point to where you'll land, then move your piece. Did you land where you predicted?
Watch for: Students who point to their landing square before moving show they're visualizing the product spatially. Those who trace their path finger-by-finger while moving reveal they're using the board to think, not just to record answers.
Listen for: Calculation strategies—skip counting ("6, 12, 18"), using known facts ("I know 3 × 6 is 18"), or adding position to product. Students who describe their process reveal which facts need more practice.
⚡ Facilitation Move: Require students to say their interpretation aloud and point to their predicted landing square before moving. The combination of verbal articulation ("4 hops of 5 squares") and physical gesture (pointing) reinforces equal groups structure more than either alone.
Strategic Movement
You're on square 47. Put your finger on the green square at 65. What roll would get you there?
Watch for: Students who keep one finger on their current position and one on the target while reasoning. This physical anchoring of both endpoints helps them frame the problem as finding factors of 18.
Listen for: Students working backward—"I need to move 18, so maybe 3 × 6 or 2 × 9." This inverse thinking (knowing the product, finding factors) develops flexible multiplication understanding.
Show me with your hands: what's the difference between "2 hops of 6" and "6 hops of 2"? Which did you choose and why?
Watch for: Students using hand gestures to show two big jumps versus six small jumps. The physical demonstration often clarifies why they chose their interpretation—"two is faster" becomes obvious when you gesture it.
Listen for: Strategic explanations showing students understand commutativity offers choice. Some haven't considered both options; this question makes explicit that interpretation matters even when the product stays constant.
⚡ Watch For: Students who consistently struggle with certain facts (often 6s, 7s, 8s). Note which need focused work outside gameplay. Quick reference to a multiplication chart during early games is fine—automaticity develops through repeated exposure in meaningful context.
Special Squares
You landed on a yellow circle and have to move backward. How does this change your strategy for next turn?
Listen for: Adaptive thinking—"Now I need a bigger roll to catch up" or "I'll aim for that green square to make up for it." Students who revise plans based on setbacks show flexible mathematical thinking beyond just calculating products.
The blue star lets you swap with any player. Who would you swap with? Show me where they are on the board.
Watch for: Students who point to specific positions while explaining their choice. The gesture of indicating "the leader" or "someone far ahead" makes spatial-strategic thinking visible.
Listen for: Reasoning that considers relative positions. This integrates mathematical understanding (comparing positions numerically) with game tactics.
Using Hopper Helper
Trace the arcs on the Hopper Helper with your finger. What does each arc show?
Watch for: Students who physically trace the arcs while explaining. This tactile engagement with the digital tool reinforces the spatial representation of equal groups along a number line.
Listen for: Students connecting visual representation to their interpretation—"Each arc is one hop" or "The arcs show 5, then 10, then 15." The Hopper Helper makes multiplication as repeated addition visually explicit.
⚡ Materials Tip: The Hopper Helper provides visual verification for students developing fluency. Have them predict their landing position with a finger point, then use the tool to check. This predict-verify cycle builds confidence better than just using the tool to find answers.
After You Play
Help students articulate strategies and insights they discovered during play. Focus on reflection and pattern recognition rather than reconstructing every move.
Show me with your hands: how did you decide between "3 hops of 6" and "6 hops of 3"? Did your strategy change as the game went on?
Watch for: Students who gesture to illustrate their reasoning—showing big jumps versus many small jumps. The hand movements often reveal strategic thinking that words miss.
Listen for: Metacognitive reflection—"At first I just picked randomly, but then I started thinking about where I'd land." Students who recognize their strategy evolved are developing mathematical maturity.
Did you notice any multiplication facts that came up more often? Why do you think that happened?
Listen for: Students connecting frequency to dice probability—"We got lots of 2s and 3s because there are six sides" or recognizing that certain products appeared repeatedly. This probabilistic thinking extends the math value beyond just multiplication practice.
When you chose between "4 hops of 6" and "6 hops of 4," did the order change the answer? Show me with your fingers how both work.
Watch for: Students who demonstrate both interpretations physically while explaining. The gesture makes commutativity concrete even when verbal explanation is incomplete.
Listen for: Students articulating commutativity in their own words—"The order doesn't matter for the answer" or "Both ways give you 24." The game provides repeated evidence of this property through experience, not just memorization.
Point to a moment on the board where landing on a special square changed the game. What happened?
Watch for: Students who point to specific squares while narrating. Using the physical board to support reflection turns it into a shared artifact for analyzing their mathematical decisions.
Listen for: Students describing strategic consequences—"I landed on green and jumped ahead" or "The swap put me way back." This spatial reconstruction connects their decisions to outcomes.
Extensions & Variations
Larger Factors
Use dice showing 4-9 or 1-12 for students ready for harder multiplication facts. Extends practice to the full range of single-digit multiplication while keeping the same structure.
Target Landing Challenge
Before rolling, players predict a target square they're trying to reach. Points for landing exactly on target. Emphasizes strategic planning and working backward from products to find factors.
Triple Dice
Roll three dice and choose any two to multiply. Players announce their choice before calculating. Adds strategic selection and deciding between multiple multiplication options.
Cooperative Goal
Teams work together to get all members to the trophy in the fewest total turns. Shifts focus from competition to collaborative problem-solving while keeping the multiplication practice.
Floor Number Line
Create a numbered path on the floor with tape. Students physically hop to embody "3 hops of 4 squares" with their whole bodies. This full-scale spatial experience makes equal groups structure concrete for students who need it.
Reverse Engineering
Show students a completed game path traced on a blank board. Challenge them to identify what dice rolls could have created that path. Develops factor pair recognition and inverse multiplication thinking.
Practical Notes
Timing
A complete game takes 20-25 minutes. First-time players benefit from a demo round where you verbalize each interpretation choice and movement. Physical setup takes 2-3 minutes—don't rush this, as students need to understand the board layout and special squares before playing.
Grouping
Pairs or groups of three work best. With four or more players, turns take too long and students lose engagement between moves. Pairs allow more frequent practice and keep mathematical thinking active for both players.
Materials
Provide physical dice OR digital dice with Hopper Helper—having both lets students choose their support level. Students developing fluency often start with Hopper Helper for verification, then transition to mental calculation as confidence grows.
Common Errors
Watch for students who add instead of multiply (responding to "3 hops of 5" with 8 instead of 15). This shows incomplete understanding of equal groups—pause the game to work through examples with physical materials before continuing. Another common error: forgetting to apply special square consequences because students focus only on their calculated move.
Assessment
Observe which facts students calculate quickly versus which require counting or tool support. Note students who strategically use commutativity versus those who don't consider both interpretations. Listen for "hops of" language—consistent use shows students are internalizing equal groups structure beyond just the game.
