Learning Objectives

Indicator: K1.5.1.1.7 - Compose and decompose numbers up to ten

By the end of the lesson, learners can:

Show that a group of up to 10 objects can be split into two smaller groups (decomposing), for example, 10 bottle tops as 6 and 4, or 5 and 5.
Put two smaller groups together to make one whole group (composing), for example, 3 dots and 2 dots make 5 dots.
Look at a dot card (0 to 10) and say the two parts they see, such as “I see 3 and 2” for a card with 5 dots.
Draw a line or circle to separate dots on a card into two parts and describe the parts in their own words.
Work with a partner to decompose numbers in different ways and talk about their work, for example 7 as 2 and 5, 3 and 4, or 6 and 1.

This lesson builds on the independence theme from Week 11. Learners already know about Ghana’s Independence Day and have been retelling the story. This week, they use bottle tops and dot cards in the colours of the Ghana flag (red, gold, green) to practise composing and decomposing numbers. Later in the week, they will sing the national anthem and create dance movements, so today’s counting work prepares them to count flag colours and dance steps.

Exemplars (from the NaCCA curriculum)

Learners decompose a group 10 bottle tops, e.g. 6 and 4 or 5 plus 5. Teacher Scaffold learners to understand the terms Decomposing and composing numbers. Composing means putting numbers together to make a whole and Decomposing means breaking down numbers into their sub-parts.
Learners also use dot cards to decompose numbers (0-10), Learners look at a dot card (e.g. with 5 dots) and say how many dots they see' If the teacher asks, how many dots do you see?
The child says, 'I see 3 and 2 dots'
*
Have learners draw a line to join or circle the 3 dots and 2 dots separately e.g. Learners repeat activity with different number of dots
5 2 and 3 4 and 1
*
Give learners cards with different number of dots e.g. 5, 6, 9, etc. and in pairs let them play the game "Pick and circle" (cut out cards with different number of dots. Write two figures under each circled dots into which the dots should be decomposed. Have learners decompose the dots in different forms and talk about their work e.g. 6 (2 and 4, 3 and 3, 5 and 1), 7(2 and 5, 3 and 4, 6 and 1), etc.
