Number Types
9, 15, 18, and 30 are all multiples of what number
Three
Quadrilaterals
Give an example of an Obtuse Angle measure.
Answers will vary. Any example from 91-179 degrees is correct.
Compare the fraction 3/8 to 1/2 and explain how you know it is less than, equal to, or greater than 1/2.
3/8 is less than 1/2 because 4 is half of 8 and 3 is less than 4.
What number is 10 times greater than 120?
1,200
9 is composite. It has three factors: 1, 3, 9
I have four sides and four right angles. My opposite sides are congruent but not all of my sides are congruent. What am I?
Rectangle
Find and name a pair of parallel lines that you see in the classroom.
Answers will vary. Lines should never touch and should always be the same distance apart.
If 4/9 of my beads are blue and 2/9 of my beads are green, what fraction of my beads are yellow?
3/9 are yellow (4/9 + 2/9 + 3/9= 9/9)
If I know the Total and the IEG in an equal groups problem, what operation should I use to solve?
Division
What are two different ways you can describe the number two.
Even, Prime, a factor of 4, 6, 8, etc.
I have three sides. None of my sides are congruent.
Scalene Triangle
A straight angle was decomposed into two smaller angles. One of the angles measured 110 degrees. What is the measure of the other angle?
70 degrees
Which fraction is greater and how do you know:
5/9 or 5/12
5/9 is greater because 5/9 is greater than 1/2 and 5/12 is less than 1/2.
Sia multiplied 8 x 3,000 and got 2,400. Explain why Sia's product is not reasonable.
2,400 is not reasonable because when we multiply whole numbers, the factors can't be greater than the product.
List the first 10 multiples of 8.
8, 16, 24, 32, 40, 48, 56, 64, 72, 80
What is the difference between a square and a rhombus?
The square has four right angles and the rhombus does not have right angles.
If I make 3 quarter turns of a full circle, how many degrees will I turn?
270 degrees
Rename 38/9 as a mixed number.
9/9 + 9/9 + 9/9 + 9/9 + 2/9 = 4 2/9
Explain how you know when a comparison problem is multiplicative and explain how you know when a comparison problem is additive.
When the problem is multiplicative, there will be language like "times as many/times more" or "times less/times fewer." If the problem is additive, there will be language like "more" and "less/fewer" without the word "times."
List all of the factors of 56.
1, 2, 4, 7, 8, 14, 28, 56
Which has more lines of symmetry: an Isosceles Triangle or an Equilateral Triangle. Explain how you know.
An Equilateral Triangle has more because all its sides and all its angles are congruent. As a result, it has three lines of symmetry. An Isosceles Triangle only has one line of symmetry.
Intersecting lines cross at any angle. Perpendicular lines cross to form a 90 degree angle.
5 x 3 3/7 = ?
17 1/7
What are four different ways we might have to interpret a remainder in a division problem?
1) Ignore the remainder
2) Add one to the quotient to add another group.
3) Share the remainder.
4) The remainder is the final answer.
