An elementary math app for learning decimals (0.1 & 0.01) using a 100-grid. Color in squares (0.01) and rows (0.1) to build decimals like 0.37, compare sizes side-by-side to see that 0.3 is bigger than 0.25, and practice addition by carrying over to 1 when the grid is full!

About this app

This interactive educational tool helps elementary school students understand decimals (0.1 and 0.01) using a visual 100-grid model. Users can click to paint squares, where each individual square represents 0.01 and a full row of ten represents 0.1. The app features dedicated modes for creating decimals, comparing two decimal numbers side-by-side, and adding decimals visually with carry-over support.

Use cases

  • Elementary school teachers illustrating decimal place values during math lessons
  • Parents helping children visualize and understand how 0.1 is larger than 0.09
  • Students practicing basic decimal addition and comparing numbers on their own

Features

  • Interactive 100-grid system where tapping individual cells colors them to update the decimal value in real time
  • Stepper adjustment buttons to quickly increase or decrease values by 0.1 and 0.01
  • Side-by-side comparison mode that visually shows which decimal is larger based on colored grids
  • Addition practice mode showing visual carry-over when the sum of two decimals exceeds 1.0
  • Breakdown of decimal values into equivalent fractions and place value components
