What we are learning

Complete symmetrical patterns and continue growing sequences.

You will need: Pencil, Ruler, Small mirror (optional), Squared paper

Warm-up

Hold a mirror against a drawing. What do you notice about the two halves?

1Finish the other half

Draw the missing half so the picture is symmetrical.

3Growing patterns

Continue each pattern for two more steps and write the rule.

1. 1, 3, 5, 7, … rule:
2. 2, 4, 8, 16, … rule:
3. 1, 3, 6, 10, … rule:
4. 100, 90, 80, … rule:

4Pattern in shapes

Step 1 uses 3 sticks, step 2 uses 5, step 3 uses 7. How many for step 5? Show your thinking.

How I worked it out

5Design a tile

Draw one tile that has a line of symmetry, then show it repeated four times.

Tile and repeat

My tile

Repeated four times

6Practise again

Write the next two terms in each sequence.

1. 5, 10, 15, 20, …
2. 1, 2, 4, 8, …
3. 20, 17, 14, 11, …
4. 1, 4, 9, 16, …

I found the rule before I carried on.
I checked my rule works for every step.

7Explain a rule

Choose one sequence from Task 6 and explain its rule in a full sentence.

8Take it home

Find something at home with a line of symmetry. Draw it and mark the mirror line with a ruler.
