Here are the maths answers for today’s learning. Let me know how you got on.
TGB: comparing number sentences
Starter
13 + 7 = 20
14 + 6 = 20
20 – 8 = 12
20 – 19 = 1
14 + 6 = 20
19 + 1 = 20
10 + 10 = 20
Using the words greater than, less than or equal to, can you compare these number sentences? One has been done for you.
8 + 7 is greater than 7 + 6
10 + 3 is greater than 5 + 2
9 + 6 is equal to 6 + 9
8 + 8 is greater than 4 + 3
3 + 2 is less than 5 + 6
8 + 3 is less than 10 + 5
Here are some questions for you to have a go at.
Using the words greater than, less than or equal to, can you compare these number sentences? One has been done for you.
13 – 3 is less than 16 – 4
17 – 7 is equal to 15 – 5
3 – 2 is less than 9 – 7
18 – 2 is greater than 14 – 9
6 – 6 is equal to 8 – 8
19 – 5 is greater than 13 – 6
Here are some questions for you to have a go at.
Now we’re going to use the symbols <, > or = to compare number sentences. Have a go at these, one has been done for you.
10 + 6 > 12 + 2
5 + 5 < 9 + 7
7 + 6 > 3 + 3
11 + 4 = 2 + 13
7 + 7 < 8 + 8
1 + 6 = 6 + 1
Here are some questions for you to have a go at.
Now we’re going to use the symbols <, > or = to compare number sentences. Have a go at these, one has been done for you.
15 – 3 = 17 – 5
17 – 5 > 11 – 8
20 – 6 > 20 – 8
13 – 7 < 19 – 2
14 – 7 > 16 – 10
18 – 9 = 10 – 1
Challenge
Miss Lotysz has 16 sweets and eats seven of them. 16 – 7 = 9
Miss Lister has 17 sweets and eats eight of them. 17 – 8 = 9
Who has more sweets left? They both have the same amount of sweets left.
Explain your answer. 16 – 7 = 17 – 8
Extra Challenge
Miss Topliss is working out which symbol to use to compare the number sentences.
14 – 5 14 + 5
The missing symbol must be = because the numbers are the same on both sides.
Do you agree with Miss Topliss? No
Explain why. Subtracting an answer will make the number smaller.
