This week's focus is on our multiplication and division facts so it's time for Day 3 of our Numeracy Ninja challenges! Every day this week we are going to complete a Numeracy Ninja challenge where all the tables have been mixed up and it is your job to work out the missing number in each calculation.
There are 60 questions to complete each day.
Don't forget to time yourself to see if you can beat yesterday's time! If you haven't finished after 15 minutes, stop and spend another 5 minutes revising your tables please.
If you choose the higher level challenge, you are looking at all the tables from 2 X to 12 X plus their division facts.
Today's lower level challenge focuses on the 4 X table. Download the Multiplication Tables Factsheet and spend a couple of minutes practising counting forwards and backwards in 4s and looking at the related division facts. Then download the 4 X table challenge and try to complete it without any help. Lots of questions are repeated throughout the worksheet to help to reinforce your learning.
Today we are going to revisit our work on area. To begin, please log in to Education City https://go.educationcity.com/ and use the Home Improvement Learn Screen to revise finding the area of squares and rectangles. Then have a go at the Area Adventure activity which asks you to compare the area of two different shapes.
Then we are going to learn how to calculate the area of a compound shape. A compound shape is made up of two or more shapes which have been pushed together to create one larger shape, for example
The compound shape in the picture above has been made from two separate rectangles.
To calculate the area of this compound shape, we need to divide it back into two separate rectangles.
Using the measurements that we have been given, we can see that the first rectangle measures 4cm by 6cm so its area is 24cm².
The second rectangle measures 3cm by 7cm so its area is 21cm².
To find the area of the whole compound shape, we need to add 24cm² and 21cm² which gives us an area of 45cm².
Watch today's video where Mrs Bell looks at more examples of compound shapes and then download one of the activities below.
In today's reasoning challenge, we are thinking about area and perimeter.
