Week 10 - 22.06.20

Doubling 

This week we will be exploring how to double numbers and what methods we can use to help us to do this quickly and efficiently. Towards the end of the week we will also look briefly at odd and even numbers. 

Please send us any pictures of the home learning you complete this week smiley

Doubles! Doubles! song ( 1-10)

Monday: 

Today we are going to double numbers using practical resources. Doubling is the same as adding the same number twice of multiplying a number by two. When we double numbers at school we draw/make two circles (see image below) and then we would look at the number we wanted to double and put that many dots into one of the circles. We would then need to do the same number of dots in the other circle. To find the answer you would need to count the total amount of dots in both of the circles. 

 

For example, if you wanted to double 2 you would draw 2 dots in one circle and 2 dots in the other. When you count the dots altogether you should see that double 2 = 4. 

 

Today we would like you to do this practically so you will need to make two large circles (using hula hoops, sticks, saucepans etc.) and you will also need some resources to help you. Then pick any number under 10 and double it!

Tuesday: 

Today we are going to continue practising doubling but instead of doing this practically we are going to be using our drawings to help us. Remember, to double a number you will need to draw two small circles side by side and then draw the specified number of dots in one circle and then repeat this process in the other circle. After that, count the total number of dots to find the answer. 

 

Use the table below and double as many numbers as you can using this technique. Please do not feel that you need to complete all of the columns, just pick the one that best suits your child's needs.

Wednesday: 

Today we are going to be applying our understanding of doubling to help us to answer word problems. You will need to use the same method that you have used throughout this week to help you to answer these questions. 

 

Remember, with word problems it is crucial that you pick out all of the important information so that you know what the question is asking you to do. To help you with this we have made the important information bold.

Thursday: 

Today we are going to have a one off lesson that focuses on odd and even numbers. 

 

What is an odd number? Can you think of any odd numbers? 

Well done, you're right! An odd number always ends in either 1, 3, 5, 7 or 9 and if we look at the numicon tiles they will always have one 'out of line' (see the image below) - there is always an odd one out. 

 

What is an even number? Can you think of any even numbers? 

Well done! Even numbers end in either 0, 2, 4, 6 or 8 and when we look at the numicon tiles they always have 'a mate' (see the image below) - even numbers are in the 2 times table.

Activity - write the numbers 0-20 on small pieces of paper and try to sort them into odd and even numbers. You might want to make two hoops so that you can separate them from each other. Remember to use the hints above to help you and try to explain how you know whether the number is odd or even. 

 

Challenge:

  1. If you add an even number and another even number what type of number do you end up with?For example, 2+2 or 4+4.  Explore this with your grown up. 
  2. If you add an odd number and another odd number what type of number do you end up with? For example 3+3 or 5+5. Is this always true? Think of your own number sentences to check.
  3. If you add an odd number and an even even number what type of number do you end up with? For example 3 +4. 

Friday: 

Today we would like you to attempt a Friday Challenge relating to doubling. This will give you the opportunity to apply all of the skills that you have learnt this week.
