3rd Grade Lesson: My Fraction Number Story (2-day lesson)

Children create their own projects in Scratch to demonstrate what they have learned both about fractions and about programming. In addition to the base project, children may choose to work on the extension activity that challenges them to use more advanced blocks to change the background, add sound, and so on.

  • Scratch project stage depicting two sprites standing in the grass with a brick wall behind them. A cake is between the two sprites. One sprite says, "Hello, Abby! I had 1/2 of a whole cake left over".

  • Scratch code blocks which use the "say" block to create a conversation between the two sprites about who ate the most cake.

  • Scratch project stage depicting a boy running over a numberline split into five segments spanning zero fifths to five fifths. The boy is over three-fifths, thinking "I ran one-fifth of a mile."

  • 5 "I Can" statements: I can decompose or break down a story into parts and create an animation. I can write precise instructions for all the actions that need to happen for my animation to work in Scratch. I can use previously learned Scratch blocks to animate a math number story. I can compare fractions with different wholes. I can add unit fractions.

Activity Summary

Children create their own projects in Scratch to demonstrate what they have learned both about fractions and about programming. The teacher first reviews with children what coding blocks they have learned to use. Then children plan their project with the planning sheets, before continuing on to create the program. In addition to the base project, children may choose to work on the extension activity that challenges them to use more advanced blocks to change the background, add sound, and so on. If time allows, students can invite their peers to interact with and/or remix the program they have created.

Math Connections

Children plan and create a number story about fractions.

CS Connections
