Provided in this Product: 1 Blank Ten Frames-Number Bond-Fact Family Mat, 1 Blank Twenty Frames-Number Bond-Fact Family Mat, 2 Worksheets for 1 - 10 Number Bonds, 1 Worksheet for 11 - 15 Number Bonds, 1 Worksheet for 15 - 20 Number Bonds, and 1 Worksheet for 1 - 20 Number Bonds, and 1 Blank Worksheet.
Materials Needed: Number Bond/Ten Frame Mats, Two Color Counters (not provided), Worksheets, Cups or Holders for the Two Color Counters (not provided).
Start with a Number Bond having 10 as the WHOLE. Have students place 10 two color counters on the top ten frame(s) of their work mat and check to see that they all have exactly 10 two color counters.
Emphasize that Number Bonds are not always indicating Addition. Number Bonds are showing how a larger number is broken down into or built from smaller parts. Designate the left side of the Number Bonds/Ten Frames as the amount of RED two color counters and the right side as the amount of YELLOW two color counters. After establishing that all students have 10 two color counters on their top ten frame, have them break apart that amount of ten into 6 red and some yellow.
"If you have 10 counters. 6 of them are red and the rest of the counters are yellow. How many counters are yellow?"
Demonstrate how to move 6 of the ten counters to the Red Ten Frame and turn them to show the Red side.
All the other counters should be shown as YELLOW and moved or broken apart to the YELLOW Ten Frame.
Show that the number bond is 10 - 6 = (___). Have students show that the fact shown by the first number bond is 10 - 6 = 4. The number bond worksheet should also show 4 yellow as part of the first number bond and students should show 10 - 6 = 4 on their worksheet.
A separate Number Bond/Ten Frame Lesson can also be used in teaching Fact Family relationships.
The 20 Frame Number Bond Mat can be used when the whole is greater than 10.
