'Number bonds to 100' for 2nd grade
Addition - Number bonding - Number bonds to 100
Number bonding is a method for recognizing common combinations of numbers that add to a specific target number. In this topic we are looking at pairs of numbers that bond to 100. So, an obvious pair you might think of is:
50 + 50 = 100
Obviously there are many other multiples of 10 that also bond to 100:
40 + 60 = 100
80 + 20 = 100
10 + 90 = 100
One thing you will notice with the multiples of 10 is that we could knock off the final zero and think about number pairs that bond to 10. You will also notice that we can play around with these bonds to derive related facts - for instance:
30 + 70 = 100
100 = 70 + 30
100 - 70 = 30
100 - 30 = 70
Now, let's think about numbers which aern't multiples of 10 like 34 or 59. One way to quickly get their number bond pair to 100 is to work the units first and then figure out the tens. So, for 34, take the unit 4, bond it to 10 with a unit 6. This pushes the tens 3 to a tens 4. Now figure the tens bond of 4 to make 100 which is 6. So the answer is 66.
34 + ▢ = 100
30 + 4 + ▢ + 6 = 100
30 + 4 + 60 + 6 = 100
So, ... 34 + 66 = 100
Consider another example, say 22:
22 + ▢ = 100
20 + 2 + ▢ + 8 = 100
20 + 2 + 70 + 8 = 100
So, ... 22 + 78 = 100
So knowing your number bonds, or knowing how to quickly work out number bonds can massively speed up your mental arithmetic.
