For the second lesson we used the If... Then... graphic organiser to explore how a knowledge of number bonds to 100 can help with working out change from $1.00. Students then used blank number lines to find change from $1.00 and a second worksheet with some examples of buying items at "Tessa's treat store". I was able to work more closely with some students to ensure they understood the process of using the blank number lines. We also used some base 10 blocks to demonstrate a common mistake students were making which resulted in bonds to 110 instead of 100.
In the third lesson students played concentration with number bonds cards, where they had to find the pairs of numbers that add to 100. This was a great way to reinforce the pairs and an activity I will come back to in future lessons.
The worksheets for this lesson can be downloaded for free at my Teachers Pay Teachers store. The package includes:
- Three worksheets with samples and an answer key
- Number bond cards for concentration
