Maths skills to practice at home:

Practice counting in 2s, 5s and 10s!

We are working on our number bonds to 10 and using these to find number bonds to 20 and other related facts...

If I know that 6 and 4 makes 10, I also know...

6 and 14 make 20 
4 and 16 makes 20
60 and 40 makes 100
If I have 36 I only need 4 more to get to 40

The foundations of number bonds will help your child progress and make links with much of their number work. 

Let us know if you have been doing this at home so we can celebrate this with your child at school.

Try our Tens and Ones drop-pot game.

You will need:
Two small containers (cups or pots work fine).
Counters: A handful of two different kinds of counters (a few one pence and ten pence pieces are perfect).

How to play: Player one - the dropper. Player two - the counter.
Player one is the dropper and holds the ones (counters) in one hand and the tens (counters) in the other. Make one pot tens and the other pot ones. Start dropping the tens into the tens pot one at a time, waiting for player two to count them up as you drop "10, 20, 30" (go to their counting speed). After a few drops player one (the dropper) says "stop!", then starts slowly dropping the ones into the other pot one at a time. Player two (the counter) now counts in ones from where they left off with the tens, "31, 32, 33, 34". Again the dropper says "stop!" and goes back to dropping into the tens pot. The counter (player 2)  then counts on from where they left off with the ones, "44, 54, 64, 74". Then swap over and have a turn at being the other player.

The counter develops the skill of mentally increasing either the tens or ones, having to count on from where the last pot stopped. This is mentally challenging and takes practice, it is really good fun and the children have enjoyed having a go.  
Don't give up Caterpillars, practicing and having fun is the key!

Who will get to 20!

Rules: you can count on 1, 2 or 3 places, see who can say 20 first!

Online fun!

Formal methods for year 2...

Year 2 are looking at 'Column addition'. 
Place a two digit number on top of another two digit number. 
Write a T for tens at the top of the left hand column and an O for ones at the top of the right hand column.
Write in your + symbol to the left (tip - make sure it is not in any of your columns!)
First add the ones column, writing the answer at the bottom directly in line (Tip - try counting on, place the greater number in your head and count on the remaining smaller number).
Then add the tens column and write in the answer directly below. Note you do not need to add a zero even though it is a tens number... we know it is a ten because it is in the 'Tens column'. We call this 'Place Value'. 
Try column addition for:          23 + 12           42 + 16            34 + 22 

What happens if you try ....     26 + 17     Uh Oh! When I add the ones column it makes more than 10! 
The rule is that a tens number can not live in the ones column as...
The 6 + 7 = 13, this is not a ones (single digit) number!      
Don't worry just write in the 3 in the answers space for the ones column and carry the whole ten you have made into the tens column by writing a small 1 under the existing tens digits (this way you will not forget to add it in!).
Now add the tens column up. 20 + 10 + 10 = 4 tens (43). 
This is called regrouping!
Try Column addition with regrouping for:        26 + 27             15 + 16            37 + 17 

Column Subtraction works in the same way. Just write the - symbol next to your numbers to show you are taking away. Subtract the ones column first and then the tens (tip - always identify the greater number so you can place it on the top of the smaller number). Don't forget to make sure they are perfectly in line with the T (tens) and O (ones) written above. Try: 74 - 32        56 - 23       84 - 42   

Hold the phone! What if I try.... 42 - 23   When I try to take away the ones I can't!
I cant take away 3 from 2.. there are not enough numbers to take away from.
Try regrouping with your Column Subtraction!
Borrow some form the tens column to make a bigger number that you CAN take away from. 
Cross out the 4 and write 3 next to it (to show 3 tens are left in that column) 
Write the ten you have pinched in next to the ones number that was to small to take away from. Now you have 12 instead of 2! sorted! you can easily take 3 from 12... and it leaves you with a ones number (9) which is just right for the ones column. 
Finish off by taking 20 away form the 30 you left in the tens column, leaving one ten to write in the answers space of the tens column.  Was your answer 19? 
Practice is the key... do these with your adult:        56 - 37        44 - 16         65 - 28 
Ask them to set you some more... try 2 a day! little and often is the key. 

Have fun and keep practising!
