11/05/20 - Substituting shapes for numbers
This week we are going to be introducing you to algebra!
Today's work starts with replacing a number in a calculation with a shape. Use the key to help you to solve the questions below:
Now have a go at the following problem. This time you will have to work out what the numbers the shapes are representing. You may need a bit of resilience to solve this one.
Where could you start?
What can you tell from the first multiplication with three purple squares and a yellow semi-circle?
Perhaps you can use what you now know to help you with another calculation?
How will you remember what you have tried and what you have found out?
Lesson 2: Similar to yesterday's problem, see if you can solve the problem below:
Now try having a go at these 4 SATs questions. They all involve replacing shapes with numbers.
Another problem for you to solve, but today instead of shapes the numbers have been replaced by letters! Start with D =6 and work from there. How many letters of the alphabet can you solve?! Good Luck!
As this is very small to see, here it is below in a PDF file!
Lesson 4 - Using formulae
Today we are going to look more closely at formulae.
IMPORTANT! When we are recording multiplication we do NOT put the x sign, we just put the number we are timesing by before the letter. So for example:
If a = 4 and I want to say I have got 5 lots of a, I would write 5a NOT 5xa
Have a go at the questions below:
Now try these:
And finally these...(There's quite a lot here today so you might want to keep some for tomorrow! We will only be posting a few sats questions tomorrow!)
Now see if you can have a go at these SATs questions:
