Teen numbers: 10 and some more

Counting
Cover all multiples of 10 on a 1-100 grid with sticky notes. Use the grid to support counting to 100, with children using their fingers to match the 1s digits of the numbers. Emphasise numbers ending in 0 and 5.

Number bonds
With children in pairs, ask each pair to show you 10 fingers altogether, so one child might show 6 and the other might show 4. Now ask them to do this in a different way. Repeat.

Chants/Rhymes/Songs
Together, sing a song which counts to 20, e.g. Let's Count to 20 Song For Kids.

Story
Read Teeth, Tails, & Tentacles (an animal counting book) by Christopher Wormell. Together count how many legs, spots, eyes etc are on the animals (up to 20).
