Great way to develop Number Sense!!
There are two bonding race car worksheets to help students become fluent with their bonds to 100. The first race track is bonds to 100 using friendly numbers. Example: 30 + 70. The second worksheet is bond to 10 and add the rest. Example: 48 + 52. I have also shared a very good free site (Greg Tang's) that has many other practice bonding practice sheets.
Students use mental math strategies to quickly bond to 100.
It is very engaging as the students try to hurry around the track and make it to the finish line.
This activity is in our TPT Smart Board Presentation -
