Year 1 Maths Week Beginning 20.4.20 Multiplication and Division

Monday Aim: I can group objects in twos and count the groups.Starter:Count to 20 together, try whispering the odd number and saying the even numbers louder. If you have number cards sort them together into an odd and even pile, or write a list of the odd and even numbers up to 20.

Focus Activity:Ask your child to collect dolls, teddies, lego figures etc. Choose 2 figures and ask how many arms, feet, hands or eyes do they have? Add another figure, how many ears are there now altogether? Increase the amount of figures as your child shows understanding. How many more feet or hands are added each time you get a new figure? What are you counting in? Encourage your child to count in twos as they go along the figures.

TuesdayAim: I can group objects in twos and make a given total.Starter:Practice counting in twos, you could say a number your child has to get to each time e.g. “count to 16 in twos”.

Focus Activity:Using the toy figures from yesterday, pencils or pieces of pasta, can your child say how many twos make 6? Ask your child to put the 6 items into groups of 2. You could use a number line to move along as you are counting in jumps of 2. Try again with other amounts- How many twos in 10? How many twos in 8? If there are 10 items how many groups of 2 would that be?Try these challenges, you can use the number line to help.

WednesdayAim: I can group objects in twos to solve a problem

Starter:Begin with counting in 2s from 0 how far can you go?Write numbers counting in 2s with some missing spaces to fill in for example, 2,4,___,8,10 14,16,___,20.

Focus Activity:You could use your toy figures again to help today. If there were 3 figures how many knees would that be? Ask your child to answer in different ways for example, 2 times 3 is 6, 3 lots of 2 is 6 or 3 multiplied by 2 is 6, 6 divided by 2 is 3.How many toys would we need so we had 10 eyes? Think of different ways to answer this question.Now try these questions together, you could draw the pandas and rabbits or use toy figures to represent them and use pencils/pasta/pieces of grass or vegetables to share out to each animal.

When you have worked out how many, can you work out the different vocabulary to use for example, 14 divided by 2 is 7, 7 groups of 2 is 14.

ThursdayAim: I can group objects in tens and add the groupsStarter:Follow this link to play a game practicing counting in 2s, 5s and 10s http://www.sheppardsoftware.com/mathgames/earlymath/BalloonPopSkip.htm

Focus Activity:Time to move around the room- every time you jump, count 10 more. Say a number of jumps to do for example, 5, then ask what number they got to. Repeat with a few numbers. Is there a way to work out how many are in the pictures below without counting every picture? Count the top line to see they are in 10s, then go down each line counting 10 more each time. How many in each picture?

If you have a dice, number spinner or number cards, use them to select a number then count how many you would have if you had to say that amount of 10s for example, Roll so you would work out 6 groups of 10 which is 60. Repeat with different numbers.

FridayAim: I can group objects in fives and add the groupsStarter:Play Ping Pong with number doubles, say a number (start with 1-5 then progress) and your child works out doublee.g. adult says 3, child says 6 adult says 5, child says 10

Focus Activity:Ask your child to bring a small group of objects to the table e.g. pencil case, fruit bowl, lego figures. Each thing cost 5p, ask them to choose an amount of objects then work out how much it would cost counting in 5s each time. Repeat with different amounts.Look at the alien pictures below, in ‘Jingling World’ everything comes in 5s. Say together “_ groups of 5 makes _” (filling in the gaps) for example, 2 groups of 5 makes 10.
