1. Watch the opening video on simple algebra equations.
2. Here are some examples of easy algebra questions. Ready! Its easy as 1, 2, 3
5 + x = 12
5 + 7= 12
x= 7
Algebra is finding what the missing variable is. The variable in this equation is x= 7
15- x = 10
15-5= 10
x= 5
12- y = 10
12- 2 = 10
y= 2
The missing variable is x=5
Try and answer the following questions using algebra. What is the missing variable?
1. 15- x = 9
2. 6 + x = 16
3. 14 - x =10
4. 5 - n =3
5. 16- y = 6
6. 18- j =4
7. 8 + x =11
8. x + 2 = 18
9. 10- x = 4
10. 5x= 25 ( this one is multiplication)
3. Now for the next part these 3 numbers are all part of a fact family. 12, 2, 6. Using these 3 numbers come up with 2 multiplication and 2 division questions.
12, 2, 6
2 x 6= 12 and 12 / 6 = 2
6 x 2 = 12 and 12 / 2= 6
7, 4, 28
7 x 4= 28, 4 x 7 =28
28 / 7= 4, 28 / 4 = 7
Just make sure you use all your numbers it is easy! For division the bigger number goes first.
1. 10, 5, 2
2. 7, 3, 21
3. 4, 12, 3
4. 6, 24, 4
5. 3, 3, 9
