Time to think… The length of is 10cm. The width is 8 cm. The height is 12 cm. What is my volume?

Explanation The length of is 10cm. The width is 8 cm. The height is 12 cm. What is my volume?

L X W X H = 960 cubic cm

Time to think… Find the volume…

5 ft

10 ft*Width for entire objectIs 4 ft.

5 ft

15 ft

Explanation Find the volume…

5 ft

10 ft*Width for entire objectIs 4 ft.

10x4x5 = 200 15 x5x4 = 300

5 ft V=500!

Time to think… What type of angle is this?

Time to think… What type of angle is this?

Obtuse… more than 90°

Time to think… Mrs. Schuldt says a trapezoid is a polygon that

has exactly one set of parallel sides. Mrs. Nestor says a trapezoid is a polygon that

has at least one set of parallel sides. Which teacher is correct, according to the

hierarchy below?

Explanation Mrs. Schuldt says a trapezoid is a polygon that

has exactly one set of parallel sides. Mrs. Nestor says a trapezoid is a polygon that

has at least one set of parallel sides. She’s right because Parallelograms have 2 sets of parallel sides.

Which teacher is correct, according to the hierarchy below?

Time to think… Which is not a unit cube that could be used to

find volume? A. 1 in x 1 in x 1 in B. 1 yd x 1 yd x 1 yd C. 12 in x 12 in x 12 in D. 2 in x 2 in x 2 in

Time to think… Which is not a unit cube that could be used to

find volume? A. 1 in x 1 in x 1 in B. 1 yd x 1 yd x 1 yd C. 12 in x 12 in x 12 in D. 2 in x 2 in x 2 in – it must be a set unit of

measure- a foot, an inch, a meter, etc.

Time to think… What names describe the shapes below?

Explanation… What names describe the shapes below?

Triangle, equilateral, isosceles Quadrilateral, Parallelogram, rectangle,

rhombus, square

Explain… Why is a square a rectangle, but a

rectangle not a square?

Explain… Why is a square a rectangle, but a

rectangle not a square? A square is a rectangle because it has two

pairs of congruent sides, two pairs of parallel sides, and four right angles. A rectangle is not a square because it does not have all 4 sides congruent.

Time to think…Solve this riddle: I have two pairs of parallel sides. I have no right angles All of my sides are the same length.

What am I?

Time to think…Solve this riddle: I have two pairs of parallel sides. I have no right angles All of my sides are congruent to each other.

What am I? Rhombus

Time to think… Which word does NOT describe the shape

below? Square Rectangle Parallelogram Quadrilateral

Time to think… Which word does NOT describe the shape

below? Square Rectangle Parallelogram Quadrilateral
