Take the next step in number ordering with Monster Number Puzzles: 20–100. This playful, hands-on resource allows students to practise identifying one more and one less within the number range of 20 to 100. With engaging monster-themed graphics and 3-piece puzzles, it’s the perfect way to reinforce sequencing skills and deepen number understanding.

Each puzzle includes a central number between 20 and 100, along with a piece showing one less and a piece showing one more. Students must match the correct pieces to build a complete monster. This activity encourages careful counting, builds fluency with number patterns, and helps consolidate place value knowledge in the tens and ones.

These puzzles are ideal for independent use, numeracy rotations, small groups, or early finisher tasks. With a focus on numbers beyond the early teens, this version bridges the gap between basic number work and more complex 3-digit understanding. Simply print, cut, and laminate for a reusable classroom resource that makes number practise fun!
