Help your students build number recognition, subitising skills, and numerical fluency with these Number Detective worksheets! This engaging resource provides students with the opportunity to identify multiple representations of a given number, reinforcing their understanding of early number concepts.

Each worksheet focuses on a specific number from 11 to 20, challenging students to find and colour all the representations of that number. Representations include numerals, ten frames, tally marks, fingers, groups of objects, words and simple equations.

How to Complete:

1. The target number is located at the bottom left corner of each worksheet.
2. Students will look at the different numerical representations and determine which correctly represent the target number.
3. Students colour in the circles that match the target number.

Additional Tips:

1. Have students create their own representations using counters, blocks, or by drawing on mini whiteboards.
2. Ask students to explain why they coloured specific circles to reinforce their understanding.

Extension Ideas:

1. Asking Questions: Challenge students by asking questions, such as: What is one more than the target number? What is one less than the target number?
2. Addition Problems: Have students record other addition problems that add to the target number.

This Number Detective resource is a fun and effective way to build foundational number sense skills.
