### Teaching and Group Activities for Understanding

**Day 1 Teaching**

Display a picture of lots of different 2-D shapes. Discuss with children how we can identify and categorise these shapes and then represent how many there are of each type in a Block Graph. Demonstrate how to count the shapes and create a tally chart. Then model drawing the block graph.**Group Activities**

Use the in-depth problem-solving investigation Sticky Data’ from NRICH as today’s group activity.

Or, use these activities:

-- Draw a block graph to show numbers of different types of 2-D shape.

-- Make statements about the data in a series of block graphs.

**Day 2 Teaching**

Show a picture of different capital letters. Discuss how we can identify different lines of symmetry in these. Come up with 4 categories. Create a tally chart to count the letters in each type and then model drawing a pictogram to represent this information.

**Group Activities**

-- Conduct a survey and create a pictogram for the data.

-- Use the data presented in a pictogram to create labels and a title, then make statements about the data.
