Explain the difference between a whole number and a fraction.
Whole numbers are complete numbers, while fractions are parts of those numbers. A whole number can be represented by any fraction with the same number in the numerator and denominator (ex. 5/5, 9/9, etc.). A fraction is a part of the whole (4 out of 6 cats are girls).

Mike has three-hundred five copies of the notes for the presentation. 78 of them blow away in the wind on his way in to the building. How many copies of the notes does he have now?
ALL should solve in Math Notebooks. Have a student model on on the board how to solve.
Use a problem solving strategy. Draw a bar model with 305 in all at the top and 78 as one piece. ? is the missing piece and when we have a missing piece, WE SUBTRACT.
Subtract

What is the numerator in this fraction:
3/4
What is a numerator?
The numerator is 3.
Numerator is the amount of pieces out of the whole that have something in common. (ex. 3 out of 4 of the cars are white.)

Explain what AREA is in your own words.
Area is the space INSIDE a polygon's peRIMeter. (Remember, RIM = SIDE OR EDGE, like on a can.)

Georgia makes five dozen brownies for the bake sale. She gets 20 more from her friend Stacy who agreed to help her.
How many brownies does Georgia have now?
ALL should solve in Math Notebook. Have one student model on the board how to solve.
TWO STEPS:
1) We need to know how many in all. We must multiply 5 times 12 (a dozen).
12 x 5 = 60 brownies.
2) Stacy gives Georgia 20 more brownies. She has more, so we need to ADD.
60 + 20 = 80 brownies in all.

What is the difference between the number of faces a rectangular prism has and the number of faces a pyramid has?
A rectangular prism has 6 faces and a pyramid has 5, so the difference is 6-5=1.

Which fraction is GREATER? Use equivalent fractions to help you.
2/8
or
3/4?
3/4 (or 6/8, its equivalent fraction) is greater than 2/8.
3/4 > 2/8

A figure has the perimeter of 46. It has six sides equal to the following:
7 in.
7 in.
3 in.
11 in.
11 in.
? ___ in.
How many inches is the missing side equal to?
7 inches
7x2 = 14
11x2 = 22
14 + 22 + 3 = 39 in.
46 in. - 39 in. = 7 in., so ? = 7 in.

Kate buys 56 boxes of animal crackers for her whole school. If she wants to share them equally between seven grade levels, how many boxes will each grade level get?
Students should try to solve alone. Then, have a student model.
We need to divide since we are SHARING/splitting/dividing the boxes equally. 56 boxes divided into 7 EQUAL groups gives each grade level 8 boxes to share.
56 divided by 7 = 8

B. Polygons must have at least 3 sides.
C. Polygons must be quadrilaterals.
D. Polygons must be closed figures with no gaps.
Answer: C. Polygons have at least 3 straight sides and no gaps...they are completely connected the whole way around their sides.

If the space on a number line in between the whole numbers 2 and 3 is divided into four equal parts, what FRACTION is each of those parts worth? Draw a picture to help if needed.
Each part is worth 1/4, or one fourth, since there are 4 PARTS that make up the WHOLE NUMBER.

Explain the difference between a two-dimensional figure and a three-dimensional figure. Mention their attributes (edges, faces, sides, vertices).
A two-dimensional figure is flat (has perimeter and area) and has sides and vertices only.
A three-dimensional figure takes up space (has volume) and has edges, vertices, and faces.

Make a DOT PLOT using the following information:
Favorite Ice Cream Flavors
Mint: 4
Vanilla: 3
Cookies and Cream: 10
Chocolate: 2
Rocky Road: 1
The number of dots = the number of people who liked that flavor. Basically a bar graph, but with DOTS instead of a bar.
