Basics on the topic Composing Shapes— Let's Practise!

Let Razzi help you practise how many shapes compose, or make up, another shape!

Transcript Composing Shapes— Let's Practise!

Razzi says get your fingers ready to count because today we're going to practise composing shapes! It's time to begin! In maths, composing means putting smaller things together to make a bigger one! How many squares compose, or make up, this rectangle? One, two, three! Three squares were put together to make this rectangle. Did you get three as well? Let's do another! How many triangles compose, or make up, this square? One, two! Two triangles were put together to make this square. Did you also count two? Let's try the next one! How many triangles compose, or make up, this larger shape? One, two, three! Three triangles were put together to make this larger shape. Did you say three too? Here's the next problem! How many little triangles compose, or make up, this bigger triangle? One, two, three, four! Four little triangles were put together to make the larger one. Did you also count four? Let's do one more! How many little squares compose, or make up, this bigger square? One, two, three, four! Four little squares were put together to make this larger one. Did you say four too? Razzi had so much fun practising with you today! See you next time!
