Basic shapes  review
This is a review lesson about basic shapes (polygons), meant for third grade. It contains varied handson (drawing) exercises and tilings about triangles, quadrilaterals, pentagons, and hexagons.
If a shape has three vertices (corners) 
If a shape has FOUR vertices
and four sides, 

If a shape has FIVE vertices 
If a shape has SIX vertices 


1.
Draw two pentagons here by drawing
dots and connecting them with lines.
Remember, your pentagons don't
have to look “regular” or nice. You
can draw them to look “funny,” too,
as long as they have five sides and
five vertices.
2. What shape is formed if you place the bolded
sides of the two figures together?
You can trace the shapes and cut them out.
a. ____________________________________ 
b. ____________________________________ 
c. ____________________________________ 
d. ____________________________________ 
3. Draw a straight line or lines through the shape and divide it into other shapes!
a. a square and a rectangle 
b. a triangle and a pentagon 
c. three rectangles 

d. two quadrilaterals 
e. two parts that are 
f. four triangles 

g. four triangles 
h. a triangle and a pentagon 
i. four quadrilaterals 
4. Divide the pentagon and
the hexagon into new shapes using one straight line. Notice: your
line does NOT have to go from corner to corner. Write what
new shapes you get.
a. 
b. 
c. 
d. 
5. Continue the tilings so they fill the grids, and name what shape(s) are used in the tiling.
a. ________________________ 
b. ________________________ 
c. ________________________ and ________________________ 
6. Design your own tilings here.
