### Maths Week Question: Week 2

This week you have the answers, it’s your turn to find the question?

Junior/Middle School:
What is the equation?

equation
• a mathematical statement containing an equals sign,
to show that two expressions are equal.
EXAMPLES: 2 + 2 = 4,
5x + 10 = 35

Middle/Senior School:

10 is the fraction of a number what could the number and fraction be?

(experiment with different fractions).

1. Tekau ma whitu - 17
- 5 + 2 = 7
- 4 +3 = 7
6 + 1 = 7
7 + 0 = 7
107 - 100 = 7
7 - 0 = 7

1. Great work Room 21 and Group 17. You are starting to use a variety of questions and not just using the addition sign.

3. Tekau ma ono
6 + 1 = 7 and 1 + 6 = 7 (Reversibility rule)
4 + 3 = 7 and 3 + 4 = 7 (Reversibility rule)
1 x 7 = 7 and 7 x 1 = 7 (Reversibility rule)
10 - 3 = 7
3 + 7 = 10 (Part of our Family of facts)
20 - 13 = 7 because 10 -3 = 7 and then add another 10 so its becomes 13.

4. I like to use tricky ways to answer this Question!
Like...
7x1=7 and you switch it around
Also 20-13=7.

1. Thank you for commenting Shavaun, I also like the more tricky answers too. Do you have anymore?
How about 50 - 43 =?

5. 3+4=7 6+1=7 5+2=7 7-0=7 8-1=7 9-2=7 by alexandra.
7x1=7

6. 3+4=7 6+1=7 5+2=7 7-0=7 8-1=7 9-2=7 by alexandra.
7x1=7

7. By Alexandra
3+4=7 20-13=7 1x7=7 10-3 = 7 5+2=7 6+1=7 7+0=7 3x2+1=7 30-23=7 0+7=7

1. Wow Alexandra! You have worked really hard on this problem. I like how you have used addition and multiplication. Keep it up!

8. alexandra 10-3=7 20-13=7 30-23=7 40-33=7 50-43=7 60-53=7 70-63=7 80-73=7 90-83=7 100-93=7 103103=7
120-113=7

9. Tekau ma iwa
Grace - 3 + 4 = 7, 6 + 1 = 7, 5 + 2 = 7, 7 + 0 = 7, 4 + 2 + 1 =7, 6 + 0 + 1 = 7, 6 divided by 2 is 3 + 4 = 7
Tanya - 28 divided by 4 = 7
Isabelle - 3 + 4 = 7 , 8 - 1 = 7, 4 + 2 + 1 = 7, 10 - 3 = 7
Vera - 3 + 4 = 7, 2 + 5 = 5, 6 + 1 = 7, 7 - 0 = 7, 8 - 1 = 7, 10 - 3 = 7
Peyton - 7 + 0 = 7, 3 + 4 = 7

10. Tekau ma waru
Hamish - 100 - 100 + 100 - 100 + 7 = 7, 200 - 200 + 7 = 7, 200 - 100 - 50 - 50 + 7 = 7
Max - 100 - 100 + 7 = 7, 13 - 6 = 7, 10 - 3 = 7, 5 + 2 = 7, 6 + 1 = 7
Faith - 0 + 7 = 7, 100 - 100, 11- 4 = 7, 3 + 4 = 7, 15 - 8 = 7, 8 - 1 = 7, 29 - 22 = 7

11. i also like big number,s to. math is fun!!!!
