Perform Math Operations

Enter numbers, pick an operation, and watch each column animate with carries and borrows.

How to Play

How to Play

  1. Choose two operands and select an operation: addition, subtraction, multiplication, or division.
  2. Press Start to animate the vertical algorithm step by step. Pause or resume whenever you want to discuss each move.
  3. Follow the main column setup while the helper panel explains carries, borrows, partial products, or repeated subtraction.
  4. Rewind or pick new numbers to compare different scenarios (e.g., borrowing across multiple zeros, carrying multiple digits).

Knowledge Background

The game reinforces place value, column alignment, and the logic behind carrying/borrowing. Students see exactly why digits shift left, why we regroup tens, and how partial sums/products assemble the final answer.

Why This Helps Kids

Instead of memorizing procedures, learners watch each step animate with color cues and narration. This supports conceptual understanding, especially for students who need visual scaffolding.

Extensions & Teacher Tips

  • Pause after each animation to let students predict the next move.
  • Have learners narrate the reasoning (“We borrow 1 ten because the ones digit isn’t large enough”).
  • Connect to word problems by entering the numbers from a story and describing each step aloud.
  • Pair with manipulatives (base-ten blocks) for a concrete representation.

Build Programs with Blocks

Explore entry-level block coding with Draw Turtle Shapes and watch the turtle animate every command.

Draw Turtle Shapes

Drag forward, left/right, and repeat blocks to choreograph the turtle.

Open Draw Mode

Program Turtle Shapes

Pick a fun program or write your own turtle commands. Try commands like forward, left/right, repeat, penup/pendown, and setxy.

Pick a preset or write your own program.

Commands Cheatsheet

  • forward <steps> - move forward on the grid.
  • left/right <angle> - turn clockwise or counter-clockwise.
  • repeat <n> [ ... ] - run the commands inside the brackets n times.
  • penup / pendown - move without drawing, or resume drawing.
  • setxy <x> <y> - jump directly to a coordinate.
