MATH: Doodler Dice Rollers
In this activity, students work in pairs to doodle dodecahedrons (12-sided) and icosahedrons (20-sided) to use in a math game that practices order of operations. Students will then create their own Doodle Dice Roller games to practice math skills.
Knowledge
Students have
practiced multiplication and division with single, double, and triple digit numbers.
practiced order of operations, i.e., parentheses, exponents, multiplication, division, addition and subtraction, also known as PEMDAS.
practiced using the 3Doodler.
practiced multiplication and division with single, double, and triple digit numbers.

Objectives
Students will
use a 3Doodler and stencil to doodle dodecahedron and icosahedron dice.
use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
combine addition and multiplication to create a simple expression, e.g., 5 x (20 +13) = x

Materials
Students will need
3Doodler (1 per pair)
10-sided dice (1 per pair)
lined paper (1 per pair)
pencil (2 per pair)
3Doodler (1 per pair)
10-sided dice (1 per pair)

Lesson Plan
Instructions
Step 1
Students will work in pairs to doodle their own dodecahedron and icosahedron dice (one of each).
Step 2
Demonstrate how to use the stencils on the Doodle Rollers Dice Template in order to doodle each die. Model how to fold and then weld together each side of the polyhedra dice.
Step 3
Share the game: Doodler Dice Rollers. Explain the rules of the game. Students play in pairs or trios. Each player takes a turn rolling the three dice and creates an expression that includes three different operations, i.e., addition, multiplication, subtraction and division.
*Tailor this game to meet the ability level of your math students. The answer to each expression is recorded as the player's score for the round. The player with the highest score at the end of the game wins.
Step 4
Pass out pencils and lined paper for students to record each math expression, answers and scores for each round.
Step 5
Variation on the game: If a player watching notices a way to create a higher score with a different expression and the same numbers, that player gets to "steal" the score.
