Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Point A is at (3, 3). It is moved 4 to the right and 3 up. Where does it land?
- (6, 7)
- (7, 3)
- (7, 6)
Show answer
(7, 6)
Hint: Add to x for moves right. Add to y for moves up.
Question 2
How many pairs of parallel sides does a rectangle have?
- 2
- 5
- 4
Show answer
2
Hint: Parallel sides never meet. The top and bottom are one pair. The left and right are another.
Question 3
What are the coordinates of point A? The first number is across, the second is up.
- (2, 3)
- (4, 2)
- (3, 2)
Show answer
(3, 2)
Hint: Go across to find x first. Then go up to find y.
Question 4
Point A is at (4, 1). It is moved 4 to the right and 2 up. Where does it land?
- (6, 5)
- (8, 3)
- (8, 1)
Show answer
(8, 3)
Hint: Add to x for moves right. Add to y for moves up.
Question 5
After a translation or a reflection, is the shape still the same size?
- No, it gets smaller
- Yes, it is the same size and shape
- No, it gets bigger
Show answer
Yes, it is the same size and shape
Hint: These moves do not stretch or shrink a shape.
Question 6
What are the coordinates of point A? The first number is across, the second is up.
- (7, 1)
- (1, 6)
- (6, 1)
Show answer
(6, 1)
Hint: Go across to find x first. Then go up to find y.
