Product Details

This pack is designed to provide you and your students with hands-on, differentiated activities and games to develop skills and fluency when learning number bonds to 20.

Activities start at the concrete and move to the abstract in order to create a solid understanding about number combinations that add to 20.

These activities are ideal for differentiated whole class lessons, math rotations, morning work, intervention activities in small groups to support or extend students, fast finisher games or to send home for additional practice.

Tasks have been carefully created to meet the common core standards and Australian curriculum outcomes for this grade level and will build proficiency, fluency, and confidence.


We have included a teacher differentiation guide to help you cater for the individual learners in your classroom. We have also included different variations of games to make differentiation as easy as possible.
