We have been learning to add and subtract mentally. This includes learning skills that come in very handy when you are older and calculating with larger numbers. Learning that 2 + 6 = 8 can be used later on in school life to calculate 0.02 +0.06 = 0.08.

 

The children should know their number bonds to ten and twenty and be able to use them to calculate.

 

The best way to teach number bonds is to use games. Which games work best is dependent on the age of the child and their understanding of numbers and their relationship to each other. The more familiar children are with numbers the easier it is for them to learn any form of maths. So, the number one rule is to make numbers a daily part of even very young children’s lives. Singing counting songs, showing them cartoons with number recognition and counting weaved into the story help a lot. However, far more effective is to build numbers into play. For example, using blocks.

 

Block Games for Number Bonds

To teach the number bonds for 3 lay out 3 blocks on the floor and ask your child how many blocks there are? Then tell the child you are going to move some blocks, move 2 aside and ask the child how many blocks you have moved. When they answer correctly ask them how many blocks are left?. Finally move the 2 blocks back into the original pile and ask them:-

How many blocks are in the pile now?

By doing this you have just shown your child that 3 – 2 = 1 and 1 + 2 = 3. Repeat the process removing and adding back just one block and you have just reinforced the other part of the number bond which is 2 + 1 = 3 and 3 – 2 = 1. When your child can follow this block game and answer correctly you will have successfully taught your child one of the number bonds for the number 3.

Other Games For Number Bonds

For older children rolling 2 dice and asking them to add the dice together is a good way for them to practice their number bonds. As is getting them to help you to lay the table, but only give them enough plates for some of the guests. Then ask them to work out how many more plates are needed and tell you. If you have 10 guests give them 7 plates and let them tell you they need 3 more.

 

Reinforcing Number Bonds Using Everyday Situations

Learning number bonds is key to a child’s future maths success. The children that do best at learning number bonds have the support of their parents and the rest of their family. They are given the chance to practice basic addition and subtraction, which is really all number bonds are, in their daily life.
An example of this is arranging a family party and asking your child to work out how many guests are expected in total. They will know that your sister’s family consists of 4 people your own family has 5 people in it and that Nan and Granddad together make 2 people. So with the aid of a piece of paper, their own fingers, M&Ms or blocks can add 5 to 4 to make 9, then add 2 to that to make 11.
You can carry things even further by asking your child to work out how many sandwiches are needed. For example 11 people are coming, but Granddad does not eat sandwiches, so 11 – 1 means you need enough sandwiches for 10 people. For each person who eats sandwiches you need 2 each, so 10 + 10 = 20 sandwiches.
Telling a toddler they have 2 feet when you put on their shoes is a way of helping them to understand that 1 + 1 = 2.

Bridging ten

Bridging Ten

 

10/10/16

This week we have been teaching the children to add a single digit number to another number by bridging ten. This is an essential skill later on in maths and helps quick addition of number mentally.

 

Before they can bridge ten, the children need to know their number bonds to ten e.g 1+9, 2+8, 3+7, 5+5,  6+4 etc You also need to know how other numbers are made e.g. 6  0 + 6,  1 + 5, 3 + 3, 2 + 4, etc.

Here is a clip we used in class. When you bridge ten you use the numbers to make ten first and then add the remaining number.

  e.g. 9 + 8 = 9 + 1 + 7= 17  because 9 + 1 = 10     8 - 1 = 7  so 10 +7 = 17

 

Please come in and ask if you are unsure or would like more information. All the children are encouraged to use cusinaire, and the challenge is to be able to draw a numbeline, as shown in the video clip.

 

We began with numbers such as 9+8=  and 7+6 = 

Once children grasped the idea, we then moved onto other numbers  19 + 8 =   17 + 6 =   or 59 + 8 =  37 + 6 =
