Learning intention
Students will learn how to:
add within 5 using concrete materials.
Success criteria
I will know I have been successful if I can:
add 2 groups of objects by counting carefully.
Prerequisites
- Numbers to 5
- Counting sequence to 5
Language
Reinforce the use of informal addition language: combines with, join, all together, makes
Misconceptions
- Different-sized objects cannot be counted the same way.
Before the video
- Model the need to add 2 groups of objects together and find the total.
- Have the students provide suggestions of how to find the total number of objects.
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 |
|---|---|---|
| 1:58 | One-to-one correspondence | Why does she point at each pencil? |
| 2:05 | Finding a total | Why is she not counting the 2 sets this time (to find the total)? |
| 2:17 | Counting using fingers | Why is it useful to count using your fingers? |
After the video
Concrete addition activities:
- Provide children with 2 groups of objects or 2 sets of coloured counters.
- Have them make a total of 5 objects in various ways and record the number sentence, eg 2 and 3 make 5.
