Explanation
Ten is nine and one more. A ten-frame is full when all ten squares have a counter, five in the top row and five in the bottom row. Two hands show ten fingers, five and five. The numeral 10 has two digits: a 1 on the left and a 0 on the right. Say the number as you write it. Counting to ten is a big step: now you can count all the fingers you have.
Worked examples
Two hands show 10 fingers: 5 on one hand and 5 on the other.
Mariam’s cake stall has 10 cupcakes: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
Ten is nine and one more. Here are 9 stars and 1 more star: 10 stars.
Class activity
Ten fingers. Ask the child to show 10 fingers, then fold down 1 finger at a time while counting back from 10 to 0. Then collect 10 things, such as pebbles, in a row and count them. Change the order and count again: the number stays 10.
