If Ms. D, Ms. Felder and Ms. Weatherford decide to redecorate their rooms on Monday and by Friday Ms. D has completed 3/6, Ms. Felder has completed 3/4 and Ms. Weatherford has completed 3/8. What is the order from greatest to least of who has their rooms completed?
Ms. Felder, Ms. D, Ms. Weatherford
3/4 > 3/6 > 3/8

All lines must be straight
How many does a Triangle have?
A straight line going from one vertices to another
A triangle has 3 line segments

Ms. D's family is doing an Easter egg hunt over the weekend. After finding all the eggs they decided to count how many each person found. Avery found 27, Kyle found 32 and Keller found 41. How many eggs where hidden?
27 + 32 + 41= 100 eggs
What shape belongs to the the Quadrilateral and Parallelogram family but not the Rhombus or Square Family?
The Rectangle Family
Name 4 3D Shapes.
cone, cube, cylinder, rectangular prism, triangular prism, sphere
Can a Quadrilateral have no Parallel sides?
Yes! The Other Guys!
As long as they have 4 sides, is enclosed, has straight lines and no lines cross each other, it is a quadrilateral.
How can attributes of shapes help you to determine the name of the 2 and 3 dimensional shapes?
If the shape has Multiple Faces it is a 3D shape not a 2D
If the shape has Edges it is a 3D shape not a 2D
An Elephant normally travels 50 miles in a day. If it travels for 2 weeks, how many total miles would it have traveled?
2x7=14 days or 7+7=14 days
14 days and 50 miles each day =
10+4
10 x 50= 500
4 x 50= 200
500+200= 700 miles in 2 weeks
What Quadrilateral only has one pair of parallel sides?
Of these 4 shapes, which one is a prism?
Cone
Sphere
Cube
Cylinder
Cube
How are 2D and 3D shapes related?
They can have vertices and faces and line segments.
Tammy got a dog and needs to put up a fence in her back yard. She purchase and total of 40 feet of fence. If her yard is a rectangle and the length is 5 feet and the width is 11 feet, did Tammy purchase enough fence? Prove it :)
Yes, because to go all the way around she will need 32 feet of fence and she purchased 40 feet.
5 +11+5+11=32
Ms. Weatherford is purchasing pencils for her class. Her goal is to have enough pencils for each student to have 7 for the year. If she has 21 students in her class and has already purchased 90 pencils, how many more does she need to reach her goal?
If each student gets 7 pencils and there are 21 students, 7 x 21= 147 pencils needed
Has 90 so far
147-90= 57 pencils needed to reach her goal.
How many Vertices and line segments does a Heptagon have?
7 vertices
7 Line segments
What 3D Shapes have no vertices? Hit: There are 2 that we have talked about.
Cylinder, Sphere
Hint: There are 6
Parallelograms
Trapezoids
Rhombus
Rectangle
Square
Shapes with no parallel sides (The Other Guys)
Ms. Felder drew a shape that has a total perimeter of 42in. If there are a total of 5 sides and their lengths are 7, 10, 12 and 8, what is the length of the 5th side?
Total: 42
7+10+12+8= 37
42 - 37= 5in
The missing side is 5in long.
Ms. Felder's class is making a photo album to remember their awesome accomplishments. Each student has 6 pictures but each page can only fit 3 pictures. If there are 9 students in class, what equation would help you find out how many pages you would need for all of the students pictures?
9 x 6 / 3= 18
