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 object Is 4 ft. 5 ft  15 ft

Explanation  Find the volume… 5 ft 10 ft *Width for entire object Is 4 ft. 10x4x5 = x5x4 = 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
