2 2D shape and pattern

Continued

Choose one thing to change and write your own question to investigate.

How many patterns with lines of symmetry can be made by shading
squares?

You could change:
• the number of squares in the grid

• the number of shaded squares

• the minimum number of lines of symmetry.
Investigate your question and write your solution.

• You are specialising when you make a pattern and test it to check if it has at
least one line of symmetry.

• You are conjecturing when you write your own question to investigate.

• You are improving when you reflect on your investigation and consider how
you could improve your approach.

Look at your investigation.
• How did you make sure that you did not repeat patterns?
• Is your investigation clear and organised so that someone else

can understand what you did and what you found out?
• What improvements could you make?

Look what I can do!

I can describe the symmetry in triangles.
I can describe the symmetry in patterns.

I can create patterns with lines of symmetry.
