Scratch Jr.

Key Coding Concepts

  • Algorithms



A step-by-step set of operations to be performed to help solve a problem.

Learners will use their understanding of numeracy (including odd/even, place value, skip counting and greater than or equal to) to create a ScratchJr game.


  • Learners should have previous experience with ScratchJr
  • Learners should have had practice with numeracy skills including place value (tens and ones with learners), skip counting, spelling number words, and greater than and less than

Before the lesson...

Depending on iPad availability, this lesson can be completed in pairs, individually or set up as a math centre.

  1. Give learners 10 minutes to freely explore ScratchJr.
  2. (2-5 minutes) Review ScratchJr motion, sound, looks, and triggering blocks. (see reference guide). These coding blocks can be displayed on a Smart TV or printed off.
  3. (5 minutes) Hand out Math Land Learner Response sheet; review and answer questions learners may have.
  4. Tell learners that they are going to take Cat on an adventure to Math Land and must follow the directions in the response sheet. Using a pencil they should also complete the chart. When Cat is all done answering the questions, students can make Cat do a silly dance.

Differentiated learning:

Pre-readers: Educator could read out instructions. With support, learners can complete the chart below.

Assessment FOR Learning:

  • Listen to learners’ math conversations about number sense. Are they talking about place value? Are they able to complete the response sheet independently?
  • Listen to learners’ use of coding language. Are they identifying the names of the blocks?

Assessment OF Learning:

  • Review completed Learner Response sheet
  • Educators can also review iPads and view ScratchJr game (learners should record which iPad they used on their response sheet)


  • Provide learners with an opportunity to freely explore ScratchJr or check out other ScratchJr lesson plans on CLC.

English & Math

  • Learners can write their own instructions using mathematical terminology and give to a peer to use to create their own game.
  • Writing a math problem that Scratch Cat could solve.
  • Have learners write a reflection piece on what they found difficult about the task and how they can improve.

    The K-12 Computer Science Framework

    Although learning how to build digital projects is a key part of Computer Science education, students should also learn a wider set of skills and competencies that will help them to harness the power of digital technologies as both creators and consumers. A comprehensive approach to K-12 Computer Science education includes learning about the following five focus areas:

    View Framework ➝


    By the end of high school, students should be able to create a simple computer program.

    Computing and Networks

    By the end of high school, students should understand and be able to use the tools and devices commonly used to build digital projects.


    By the end of high school, students should be able to explain how we use computers to create, store, organize, and analyze data.

    Technology and Society

    By the end of high school, students should be able to explore the ways in which technology and society have mutually shaped each other.


    By the end of high school, students should be able to apply design principles to the digital projects they create.
