Purpose

The purpose of this activity is to help students learn groupings within 10. For example 3 and 7 make 10; 8 and 2 make 10.

Achievement Objectives

NA1-3: Know groupings with five, within ten, and with ten.

Specific Learning Outcomes

recall groupings within 10. For example 3 and 7 make 10; 8 and 2 make 10.

Required Resource Materials

Unifix cubes

Activity

- Show the students ten unifix cubes, of two different colours, in a line. Explain to the students that you have a packet of ten lollies and there are two different colour lollies in the pack. For example:
- Ask:
*How many red lollies are in the packet?*

How many green lollies are in the packet? - Confirm by counting that there are 6 red lollies and 4 green lollies in the packet, ten lollies altogether. Emphasise the number fact:
*There are 6 red lollies and 4 green lollies, that’s ten lollies altogether.* - Provide the students with unifix cubes to work with and say:
*Make some packets of lollies using 2 different colours. There need to be ten lollies in each packet.* - Once the students have made some lolly packets refocus their attention together as a group and ask:
*What numbers of coloured lollies do you have in your packets?* - Clearly state the number facts as students share their work. For example:
*Sam has 2 orange lollies and 8 yellow lollies in his packet, there are 10 lollies altogether.* - As students share their lolly packets record the number facts on the board, aiming to end with a complete list of all possibilities. For example:
*5 + 5 = 10*

3 + 7 = 10 etc
