Learning intention
Students will learn how to:
share up to 10 objects into 2 equal groups.
Success criteria
I will know I have been successful if I can:
- share objects into 2 equal groups
- check that groups are equal by counting.
Prerequisites
- Counting objects up to 10
- Understand the meaning of ‘fair’
Languages
Reinforce the use of language related to fractions and equality: share equally, half, equal groups, same
Misconceptions
- You can only halve objects, not groups of objects.
Before the video
- Discuss: When do you share? Do you share with your friends? What does it mean to share? How do you know when you have shared fairly?
- Take an apple, cut it in half and give half to each child. ‘How have I shared this apple? How much apple has each person got?’ Repeat with 2 apples. ‘When we share something equally between 2 people, they will each have half.’ ‘Half of 1 apple is half an apple, half of 2 apples is 1 apple.’
During the video
First viewing:
Watch the video without stopping or pausing. Then, ask the children to explain what happened in the video. Begin to draw out key vocabulary or possible misconceptions.
Second viewing:
| Pause point | Key learning | Action/discussion |
|---|---|---|
| 1:32 | Organizing the objects in a line makes it easy to see if they have been shared fairly | Why is it helpful to lay the rings in lines? |
| 2:28 | To share fairly each person must have the same number of objects | Invite a student to come to the board to make a fair share of 4, 6 or 8 rings. Check by first counting all of the rings, then counting the rings in each line. |
| 4:07 | You can create equal shares by each taking an object at the same time until all of the objects have gone | Provide each pair with a pile of 8 counters. Ask them to create equal shares by each taking 1 counter at the same time. Then count and check. |
After the video
Sharing objects:
- Group students in pairs and provide them with Mathletics number cards (even numbers to 10), 10 physical objects such as counters and the printable for sharing.
- Students take turns to turn over a number card and place it at the top of the printable.
- Students count out that number of objects.
- Students work together to share the objects into two equal groups and say the sentence aloud, eg 10 shared equally between 2 is 5.
Mathletics worksheet:
Can you make fair shares?
- Give each pair of students 10 counters. Ask them to explore sharing the numbers 1–10 into 2 equal groups. Which numbers can be shared equally? Record.
