How we teach it

This is what sits under the answer sheets in the app — the same cards, clips and lessons your child sees after a question.

More lessons for this topic are on the way.

One question, as your child sees it

And the answer sheet that follows a second wrong try: what we know, what we need, the steps, a check, the answer.

Judy has 16 sunflowers in her garden. The map shows their position.
path
She wants to plant some more sunflowers so that they form a symmetrical pattern using the path as the line of symmetry.
What is the minimum number of sunflowers Judy needs to plant?

Your child types the answer on a number pad.

First hint: Look at each flower and check whether there is a matching one straight across the path.

The answer sheet

A pattern is symmetrical about the path when every flower has a partner straight across it, the same number of squares away.

path

find the flowers that already match. 6 of them do: they sit in 3 pairs, level with each other across the path, so they need nothing.

every other flower is on its own. Each dashed square above is where its partner has to go, joined to it by a dotted line.

count the dashed squares: 10. So Judy plants 10, and the garden ends up with 26 sunflowers in all.
