What are number bonds?
The link below takes you to the topmarks website. The picture is to show you the menu that you will get to.
Making 10 is a great way to start checking your knowledge and then do it again at the end of the day to see if you have improved!
Have a go at this video- do you know your number bonds? Sing along and send me a video :)
Try to find 10 cubes (eg lego) that are one colour and 10 cubes that are a different colour.
If you dont have cubes, just cut paper into squares and colour them in. Instead of stacking cubes, you can put the coloured paper sqaures next to each other.
Look at the worksheet below- follow the pattern that you see on it and write your numberbonds for 10 as you go. Start with 0+10=10, then go on to 1+9=10. Remember to follow the system so you don't miss any!
Extension- draw numbers 0-10 twice on bits of paper. Mix them up and turn them face down. Turn over 2 cards- did you make a pair? if you did you can keep them but if you didn't, turn them back over and let your partner have a go! Who can make the most numberbond pairs for 10?
Use your numberbond knowledge from yesterday to complete the words problems. Make sure to use your cubes even if you find them easy as it will prepare you for the expecation of being able to explain your answer later in year 1!
Remember- you don't need to print these out, you can write your answers on paper instead.
Do you have a coathanger and pegs? if not, just use ten items to actively rehearse your numberbonds for 10. Move a peg across at a time to say the numberbond out loud "2 and 8 makes 10". Remember to work systematically to reinforce mathematical thinking.
If you start with ten pegs and there are 2 moved to the other side, how many pegs will be left on the starting side? Do this practically for all of the number bonds and introduce the subtraction sign. Can your child explain the difference between addition and subtraction?
Write the number bonds for 10 again down the side of a page. Can they write the INVERSE (opposite) on the other side? It should look like this:
This should help them begin to see links between addition and subtraction whilst still working on their number bonds.
An example would be:
Children should write: 4+6=10 so 6 more.
If they just write tthe correct number sentence then that is fine too for now.
These ones are for children that want to challenge themselves. They are quite tricky so children will need support initially to understand the they need to write 4 number sentences for each picture but you will be able to leave them after a while! Children need to write ALL the number sentences for each picture. It is time consuming but really good for those children who like to explore. It links their inverse knowledge as weell as thei numberbond knowledge.
An example of a picture and the 4 number sentences is:
2+8 = 10 8+2=10 10-2=8 10-8=2
