Students assemble four-piece puzzles that match a decimal in standard form with its word, expanded, and visual representations. Sixteen puzzles are included, offering a hands-on way to reinforce understanding.

Game #1: Monster House

Students sort colorful monsters into their correct “decimal houses.” Each house represents a decimal value (e.g., 0.32). Students identify which monsters belong by matching pictures, number lines, and word form to the correct decimal. A recording sheet and answer key are provided.

Game #2: Build a Farm

Students earn farm items each time they answer a decimal question correctly. Chance cards keep gameplay exciting and unpredictable. The first player to complete their farm wins!

Game #3: Whole-Class Game – Bucket Filler!

Set up decimal task cards around the room for students to solve. Correct answers earn entries in the classroom bucket, and winners are drawn for prizes. Task cards cover reading fractions as decimals and writing decimals in word form.

Game #4: Racing Game – Line Them Up!

Teams race to line decimal cards in the correct order from smallest to largest. Each correct match helps students review word form, place value, and standard form in an engaging competition.

All games come in both color and black-and-white versions for easy printing and reuse.
