This week have been learning how to solve subtraction problems using a number line. We know that you start at the first number (the whole number) and then look at the number you are taking away (one of the parts) and make that number of jumps back on the number line to find the answer (the other part). We must remember to jump before we count and our finger must land on a number not in the middle of two numbers. We also know that when we are subtracting/taking away the number gets smaller!
This week we have continued to develop our skills in solving subtraction problems. We have been using the part part whole model to write subtraction number sentences; two for teach model. It was quite tricky at first be we have almost got it! We have to remember that we always start with the whole (the biggest number) and then subtract one part to leave us with the other part.
Draw out the part part whole model and choose a number between 0 and 6 to put in each part. Find the whole and then write the two subtraction number sentences the model shows. See example below.
This week we began looking at Subtraction.
We have learnt that subtraction can also be known as take away and we use this sign (-). We also now know that the largest number (the whole number) has to come first as you can't take away what isn't there.
We have been using practical resources to work out some subtraction problems. Try this at home using toys, pens, pasta etc. and give your child an amount to take away from the total amount. How many would there be left?
This week we have been learning all about the number bonds to 10. Here is a game to practice your quick recall of all the number bonds to 10.
This week we have started using the Singapore Bar to help us solve addition problems. If we have two parts, we can then count them all to find the whole number. (See images below) If we know the whole number and one of the parts then we can also use this information to find the missing part.
See if you can use the Singapore Bar to find the answer to these addition problems.
4 + 3 =
5 + 2 =
5 + 4 =
7 + ? = 9
8 + ? = 10
Week Ending 5.10.18
This week we have looked at the terms greater than, smaller than and equal to. We know that if an amount is greater, we look below that amount (10 is greater than 5) and if and amount is smaller, we look above that amount (2 is smaller than 6). We have also found out the equal is when a number is the same as another (1 is equal to 1).
Could you challenge your children to think of numbers that are greater than, smaller than or equal to an amount during the day. This could be done when you see a house number, a speed sign, a number in a shop window or even around the house. This will keep the children on their toes and they may even want to challenge you!!!
Have a fabulous weekend and we look forward to seeing you on Monday.
This week we have been finding 1 more and 1 less than a number. We know that when finding 1 more the number gets bigger and we have to count on (forwards) one and that when we find 1 less the number gets smaller and we count back (backwards) one.
When playing with toys/eating dinner etc ask your child how many cars/dolls/chips/carrots they have. Can they tell you how many they would have if you gave them 1 more or if they had 1 less? Encourage them to explain how they know by saying something like "I know I would have 6 because 6 is bigger then 5 and when I count forwards 5 comes after 6."
Have a great weekend!
This week we have been learning to count forwards and backwards and using this skill to find missing numbers on a number track.
Play number ping pong - You say a number (any between 1 and 20) and your child has to say the next number. Repeat back and forth. You can change the game to be counting forwards or backwards. Children should understand that when;
Counting forwards you start from a smaller number and the numbers get bigger.
Counting backwards you start from a bigger number and the numbers get smaller.
Have a great weekend!
