Weekly Warm up (Mental Maths) - Year 1

Monday -  Use the hundred square to help you.  Count from 1 - 100, pointing to the numbers as you count.  Do you notice that all of the teen numbers are in a row, the twenties are in a row, the thirties are in a row and so on?  Count in multiples of 10.  Have you noticed that they are all in a column?  What have all multiples on ten got? Count in twos.  What do you notice? You land on one square, miss a square out and so on.

Tuesday - Have you got your Maths hats on?  Let's see if you can answer the Maths questions in the PowerPoint below (Mental/oral starter - Tuesday).

Wednesday - Number of the day activity (see PDF below).

Thursday - Count up to 100, using actions to get active at the same time.  Click the link to see the counting video.  I apologise for the American accent!

Friday - Complete the PowerPoint below for Mental Maths today.

Weekly Warm up (Mental Maths) - Reception

Monday - Practise counting forwards and backwards up to 20If you have number cards from 1 - 20 can you put them in the correct order?  Use your knowledge of adding one more to help.

Tuesday - Work out how many different ways to make eight, e.g. 3 + 5 =.  You can use eight objects to help you. Here is an examples of different ways to make 10.  How many can you come up with that total 8?

Wednesday -  Quick fire number formation -  say a number 0-10 and ask your child to write it on a piece of paper, move quickly to the next number.  Continue to practise any that your child is finding tricky.  If they can form all numbers up to 10, move onto numbers up to 20.

Thursday - Count up to 100, using actions to get active at the same time.  Click the link to see the counting video.  I apologise for the American accent!

Friday - Pick a card from your number cards from 1 - 20, can you tell me the number that is one more/one less? How did you work it out?  Can you recall these facts quickly by counting on or counting backwards?

Monday

This week we are going to be thinking about subtraction.  The work below has been separated into Reception and Year 1 work.  Please find the correct day and look for the work for your child.

Reception

Can you remember what subtraction is?  First of all let's think about finding one less of any number up to 10.  Show we 10 fingers, now take one away, how many have you got left?  One less than 10 is 9.  Let's try with the other numbers.   Once your child is confident finding one less than any given number up to ten you could extend this to numbers up to 20.

Let's continue to think about subtraction.  Work through the PowerPoint below to further understand subtraction.  At this point it is important to know that your child will understand subtraction as taking away.  Once your child has worked through the slides, please can you complete the sheet below?

Year 1

Today we are going to think about subtraction.  Remember subtraction means taking away. Today we are going to use a number line to help us count backwards to find the answer. Here is an example of the method.

You can see that you start on the number nine, jump back three (look at the arcs above the numbers - there have been 3 made because we have taken 3 away) and land on number 6.

Have a go at the next one...remember to count the jumps carefully.

Tuesday

We are going to continue to think about subtraction and spend our Maths time this morning consolidating what we learnt yesterday.  You will need to pop your Maths hats on!  Here's a little picture that I found!

Reception -

There are a selection of number sentences for you to use today (and the rest of the week!), see the attachment below.  Select a number sentence.  Can you read what the number sentence says?  Can you use some objects in your house to work out the answer?  You could use lego, or cars, or Disney princesses, whatever you have got.  Don't forget to count carefully.  Can you record your answer, using the correct number formation.

**I have attached subtraction number sentences up to 10 and then up to 20.  Please choose the most appropriate for your child.

Year 1

We are going to continue our subtraction work, using a number line to count backwards.  Can you remember the key things to help you with this method?

*Start on the biggest number

*Make sure you have counted backwards and can see the correct number of 'jumps' along the number line.

*Check your working out and write the answer, using the correct number formation.

We are working with numbers up to 20 today, so please be careful when you write the number.  For example, we don't want 91, instead of 19.  Remember to think about how many tens and ones each number has to help you.  This is very similar to yesterday but has subtraction calculations up to 20.  The idea is that your child can consolidate their understanding of subtracting,  using a number line.

Wednesday

Gold Rush!

The cowboys loved to find gold! If they found large pieces of gold they were worth more than the small pieces.  However, the land owners used to ask for a cut of the gold that they had found.

Reception

Look at this picture.

Which piece of gold is worth the most?  How do you know?  How much has the cowboy collected altogether? You can either put the number five in your head and count on two more or you can count out objects that you have in your house to help you work it out.

Oh no!  Look at what has happened now?  The land owner has come along and asked for £4!

How much will the cowboy have left?   You can count out your objects and take away 4.  You should have 3 left.     Look at how that is written in Maths 7 - 4 = 3. Discuss with your child what these symbols mean.

Here are some more for you to complete?  Can you use your addition and subtraction skills to find the answers?  Remember that you can use concrete items to help you.

Activity - Read these number sentences with your grown up.  Use your objects to find the answer?  Remember that when you take away, the number that you have started with gets smaller.

10 - 4 =       9 - 6 =        7 - 5 =        4 - 2 =      10 - 3 =

8 -  2            9 - 4 =        7 - 3 =       10 - 1 =      8 - 7 =

Year 1

Look at this picture.

The cowboy has found some gold!  The large pieces are worth £10 and the small pieces are worth £1. How much money is the gold worth?  How can you find out?  Perhaps you can put 10 in your head and count on 4 more or maybe you could use the number line.

Oh no!  Look at what has happened now?  The land owner has come along and asked for £4!

How much will the cowboy have left?  How can you work this out?  Today we are going to use a number line.

Can you remember what to do?  What was your answer?  Have a go at the next few problems before moving onto your next activity.

Activity - Make your own gold (you can use anything that you like).  The important thing is that you need something smaller to represent £1 and something larger to represent £10. Collect four pieces of gold.  How many tens have you collected?  How many ones have you collected? Add any tens, using the tens count and then add on the ones, e.g, 10, 20, 21, 22.   What is your total?  Now subtract the land owners cut. (£4) Your child could continue to use a number line or perhaps they are able to count backwards mentally.  How much have you made? Repeat this fun activity as many times as you like.   Please record the calculations that you complete, showing awareness of place value when forming numbers with 2 digits, e.g. 19 instead of 91.

Thursday

Reception & Year 1

Meet Bad Barry.  He is not a nice man!  He has been stealing money!  The Sheriff in charge can't figure out how much money Bad Barry has stolen from each cowboy!  Please can you help him?

Can you see the coins in the picture?  That is the amount of coins that the cowboy had before Barry stole any.  He had 6p!  Oh no, look at the next picture! The cowboy only has 2p left.

How much money has Bad Barry stolen?  How can you work it out?  Quick, get six 1p coins from your house and a bag!  If you haven't got 1p coins any objects will do.   You could even wear a mask and pretend to be Bad Barry!
Take some of the  coins away until you are only left with 2.  How many did Bad Barry take?

Year 1s - You could use your number line.  Start on number 6, jump back to number 2 and then count your 'jumps' to work out how much money has been stolen.

I wonder if you were right.  Let's look at the next picture to see!

Were you correct?  Did Bad Barry steal 4p? Year 1s can you complete the number sentence - what is the missing number?

Here are another few for you to try.

You have a choice today!

Maths Roleplay: If you would like to continue to play Bad Barry, you can use your number sentences from the other day or make up your own.  Choose a number sentence, e.g. 7 - 3 =.  Collect 7 items from around your house and put them on your table, the floor (it doesn't matter where), now steal 3 items and put them in your bag!  How many are left?  Can you write the answer, using the correct formation?  Repeat as many times as you like.

Worksheet - Complete the Bad Barry Subtraction worksheets below.  There is one with subtraction within 10 (Receptions) and one with subtraction within 30 (Year 1's).  Year 1's you will be able to apply your subtraction along a number line knowledge to work out the answers.

Friday

How about some online resources to consolidate your work in Maths this week?

Reception -  In this activity you can practise your subtraction with in 10.
