Question 1

two or more shapes that form one resulting shape

Answer 1

composite shape

Question 2

Answer 2

line of symmetry

prism

Question 10

sphere

Question 11

Name this shape:

Answer 11

pyramid

Question 12

Answer 12

cone

Question 13

symmetrical

Answer 13

can be decomposed into matching halves

can check this by folding a specific way and looking for a match

can create this by folding a paper in half and cutting around (for example, try making a heart by cutting half of one on a folded paper)

Question 14

side or sides
edge or edges

Answer 14

the length or width, or piece that could be measured with a ruler

the two-colour pieces of a Rubik’s cube

the edges are the outer frame of something, or the toothpicks that are put together to make a shape

fencing, related to perimeter if getting the sum of all edges

hinge point

Question 15

vertex or vertices
corner or corners

Answer 15

the pointy bits

the indented bits

the intersection of the three-colour pieces of a Rubik’s cube

where you might put glue to hold wood pieces together

the ends of the edges

Question 16

face or faces
surface or surfaces

Answer 16

may make a two-dimensional object

you can measure the area of this surface regardless if it is two-dimensional object or not, but it is really hard to measure the area when you cannot see the two-dimensional object

the length multiplied by the width refers to the surface or face of a cube or prism; there are other formulae depending on the two-dimensional object

what you can paint

Question 17

translation

Answer 17

slide

Question 18

rotation

Answer 18

turn

Question 19

reflection

Answer 19

flip

Question 20

Do geometric attributes such as edges, faces, or vertices change when a shape is translated, rotated, or reflected?

Answer 20

no

Question 21

size

Answer 21

the amount of one measurable attribute of an object or a space

generic term to describe how big something is and can be interpreted in many ways such as:

the length of an object (if you add up the outer lengths you have perimeter)

how much flat space an object covers (area)

how much a container holds (capacity)

the heaviness of an object (weight)

Question 22

length

Answer 22

the distance between two points in space

the amount of fixed space between the end points of an object

does not need to be a straight line

length can be specified such as height, width, depth based on their orientation

length remains the same if an object is repositioned but may be named differently:
in the context of a rectangle, we commonly use width for the shorter edge and length for the longer edge

measured with equal-sized units that themselves have length

Question 23

process of measuring length by using many copies of a unit without gaps or overlaps

Answer 23

tiling

Question 24

process of measuring a length by repeating one copy of a unit without gaps or overlaps

Answer 24

iterating

Question 25

comparisons of size

Answer 25

longer
shorter
heavier
lighter
too big
too small
higher
wider
deeper

Question 26

referent

Answer 26

personal or familiar representation of a known length used to estimate the length

e.g. you can use your thumb to measure an inch, or your baby finger to measure a centimeter, or a swimming pool length to measure 25 m
