Dear Year 2,
Welcome to Maths Week 5! Over the next two weeks we will be recapping the work that we did in school on shape. This page is set out slightly differently this week, as there are sometimes games or online lessons that we would like you to have a go at before you complete your problem solving tasks. Use these as much or as little as you need to depending on how confident you feel. It’s always good to recap what you’ve already learnt though!
Number Magic and Practical Activity
Have a look at these pages on BBC Bitesize before you try your problem solving task. They will help to remind you about the names of some 2D and 3D shapes. On each page, there’s a short video to watch, some little activities to complete and a quiz at the end. The 2D shape page calls the point where two lines meet a ‘corner’ for 2D shapes. Remember that we usually call these points ‘vertices’, but they can be called ‘corners’ too.
Have a look at this website, where you can make 2D shapes on a geoboard! How many different shapes can you make? Can you name the shapes that you have made?
Today you are recapping counting sides and vertices on 2D shapes. Before you have a go at your problem solving, you might find this online lesson a useful tool to refresh your memories.
Click on Lesson 1 ‘To identify shapes by the number of sides and vertices’.
Today’s maths activities are about finding lines of symmetry on 2D shapes. This online lesson recaps some of what we learnt in school. Have a little look at it and complete the activities, especially if you think you might be a bit rusty with finding lines of symmetry! Scroll down to Lesson 3 ‘To recognise lines of symmetry within 2D shapes’.
We would also like you to have a go at these symmetry games:
Today you are recapping how to sort 2D shapes. In school we learnt how to sort shapes into a Venn diagram:
Remember, shapes that could go in both categories go in the middle, and shapes that can’t go in either category go outside the Venn diagram.
We also touched on Carroll diagrams. Remember that you have to read down and across. Have a look at this example:
