## Purpose

To identify digits written incorrectly and correctly write them.

Write several digits on the board in random order. Include several digits that are written backward or upside-down. Have children look at the numbers and raise a hand if they see something wrong. Then ask a volunteer to erase one of the digits that is not written correctly.

Part 1 involves numbers 0 to 5. Part 2 includes numbers to 10. The extension moves to include numbers to 20.

I’m going to write some numbers on the board. If you see something that doesn’t look correct, raise your hand. (Next, invite children to the board to erase and rewrite each digit written incorrectly).

- Write numbers 0 to 5 in any order, some written backwards or upside-down.

*While children are enjoying their building of mastery, feel free to repeat. When children are eager for more, try Part 2.*

- Add on the numbers 6 to 10 in any order, some written backwards or upside-down.

*As always, when children seem excited for a new challenge, move on.*

- Add on the numbers 11 to 20 in any order, some written backwards or upside-down.
