Today's Lesson
Introduction
Show the 📄 2D shapes sheet to your student.
Say: ‘We are going to find out how many of each shape there are and display this information on a block graph.’
Look at the picture. What different types of shape are there?
Together, make a list of the different shapes: squares, rectangles (oblongs), hexagons, pentagons, circles, triangles. Ask your student to check that all shapes have been identified.
Say: ‘Now count and record the number of each shape with tally marks. Begin with the oblongs; make 4 tally marks, then join them with the fifth and add 1 more tally mark for the sixth oblong (see below for how to demonstrate ‘5’).’
Count each of the other types of shape and make appropriate tally marks beside them. Once your tally chart is complete, explain that you will now use this information to draw a block graph.
Show your student the 📄 Blank block graph.
Explain: ‘The horizontal axis (at the bottom) is for the different types of shape.’
Label the horizontal axis: ‘Types of shape’. Then write the names of the shapes along the bottom, one for each column.
Say: ‘The vertical axis (going up the left-hand side) shows the number of shapes that we found.’
Label the vertical axis: ‘How many?’
Help your student to colour in the correct amount of squares for each of the shapes.
Finally give the graph an appropriate title, for example: ‘A block graph to show the number of different types of shape in a picture’.
Main Activity
Give your student a set of randomly selected 2D shapes.
Your student should sort them into shape types and use a new copy of the 📄 Blank block graph to show the shapes that they have.
Remind your student to label the two axes of the graph and to give it a title: ‘A block graph to show…’
