Kelly Warburton▸ U4: Math Connections


I really liked the addition game (created in Scratch) that was presented as a video tutorial in this course.

I had a play and created a multiplication version with an underwater theme, sound effects and a few other variations.

I thought this idea could be used in a series of lessons for Grade 5 students.

Lesson One – Watch video tutorial for addition game. As a class, create a flow chart for the steps in this game. Explore the addition game program by recreating, testing and debugging.

Lesson Two – As a class, discuss how you could use element of the addition game program to create your own multiplication program. Break down the problem into a list of steps. Choose the target audience* and focus multiplication table, discuss what your game will achieve and variations to program. Create a flow chart for your own game.

Lesson Three/Four – Program your own version of the game in Scratch, discussing, testing and debugging as you go.

Extra challenge – adding sound effects and a theme with an extra feature (eg. Underwater characters appearing with responses to users' answers).

Use efficient mental and written strategies and apply appropriate digital technologies to solve problems (ACMNA291)

*Audience could be a younger grade or their class mates. If choosing Grade 5 classmates it could be possible to program more challenging questions and assess the following:

Solve problems involving multiplication of large numbers by one- or two-digit numbers using efficient mental, written strategies and appropriate digital technologies (ACMNA100)

Digital Technologies
Define problems in terms of data and functional requirements drawing on previously solved problems (ACTDIP017)

Design, modify and follow simple algorithms involving sequences of steps, branching, and iteration (repetition) (ACTDIP019)

Implement digital solutions as simple visual programs involving branching, iteration (repetition), and user input (ACTDIP020)
