Odd & Even Number Ninja — Sort, Color & Solve

Give every object a partner. If none is left standing alone, the number is even; if one remains, it is odd. That simple test sits underneath this 10-page ninja-themed set for ages 5–7.

Children sort numbers into dojo categories, colour paths through mazes, pair pictured objects, and solve puzzles based on parity. The numbers reach 100, allowing learners to spot that the final digit tells the same story even when the number itself gets larger. Extension challenges move into odd and even sums and products for children ready to investigate what happens when two classifications meet.

The maze pages are more than decoration. A child must choose the odd-numbered route while ignoring tempting wrong turns, so each decision provides a quick classification check. If the route stops unexpectedly, go back to the last junction and test the numbers by pairing or looking at their final digits.

Use these pages as a short warm-up, a maths-centre option, or focused practice at home. The sorting activities work well before the puzzles because they make the categories visible. Later, ask the child to predict whether an answer will be odd or even before calculating; the prediction encourages attention to patterns without replacing the arithmetic.

The PDF is ready to print, and individual missions can be repeated as needed. A pencil is enough, though two small piles of counters beside the page can help when the “one left over” rule is still new.
