Splash Those Variables Away

Subject Area

Mathematics

Grade(s)

Overview

Ker-Splash is one of the interactive math games included in NCTM's Calculation Nation. Students collect tokens with variable values and combine like terms. Math strategy is required because each variable has a secret value that is not revealed until the end of the game.

    MA19.7A.21

    Solve multi-step linear equations in one variable, including rational number coefficients, and equations that require using the distributive property and combining like terms.

    Unpacked Content

    UP:MA19.8.11

    Vocabulary

    • one solution
    • no solution
    • Infinitely many solutions
    • like terms
    • Distributive property

    Knowledge

    Students know:
    • how to solve one and two step equations with one variable.
    • Write linear equations given real-world contexts.
    • That a solution to an equation can represent a real-world quantity.

    Skills

    Students are able to:
    • apply the distributive property and combine like terms to simplify an equation.
    • Recognize a solution as representing one solution, no solution, or infinite solutions.
    • Analyze and solve a real-world problem and write an appropriate equation for it that leads to a solution that can be explained within the context of the problem.

    Understanding

    Students understand that:
    • equations can now have more than one solution in given real-world scenarios.
    • The distributive property and combining like terms are essential to simplifying an equation. therefore making it easier to solve.

    Learning Objectives

    Learning Objectives

    The student will solve linear equations will one variable. 

    Activity Details

    Students should already be familiar with the concept of like-terms and how to combine them.

    Ker-Splash may be accessed either by creating student accounts (no personal information required) or as a guest. I recommend using two player accounts to allow more student interaction.

    This will work very well with an interactive whiteboard or by projecting the computer screen.

    Divide the students into two teams. Provide a process for students to take turns in making decisions. Like-terms must be combined to make room for additional coins so either the same student that made the strategic decisions or someone else may do this.

     If multiple computers are available, students could play in pairs.

    Assessment Strategies

    Assessment Strategies

    The teacher will observe students solving linear equations within the game to determine progress towards the learning objective. 

    Background and Preparation

    Background / Preparation

    Students must be familiar with the concept of like-terms and know the rules for combining them.

    If individual students will be playing, they should create Calculation Nation accounts ahead of time.
