Math-Literature book
GPSs- M4G1. Students will define and identify the characteristics of geometric figures
through examination and construction.
a. Examine and compare angles in order to classify and identify triangles by
their angles.
b. Describe parallel and perpendicular lines in plane geometric figures.
c. Examine and classify quadrilaterals (including parallelograms, squares,
rectangles, trapezoids, and rhombi) by their properties.
d. Compare and contrast the relationships among quadrilaterals.
Summary- This is a book about Mortimer the bear who is teaching about shapes and giving every
day examples of the shapes. Mortimer talks about flat shapes- circle, rectangle, square, and
triangle. In addition, Mortimer talks about solid shapes- sphere, cylinder, cube, and box.
Mortimer also has a little trouble at the end remember all the shapes and need help from the
reader to name the shapes.

2. Activity #1- Angles at home
Mortimer drew the picture below, which has several angles. Find and label each
right angle, acute angle, and obtuse angle. Count
them and complete the sentences below.
Right angle
There are ________right angles.
There are ________acute angles.
There are ________obtuseangles.

3. Activity #2-Real World Quadrilaterals
Mortimer needs help grouping the words below (words can be used twice). Cut out
the words and group them with correctwords. Paste the groups on another sheet of
paper. Blank spaces can be used to write in words that can be used twice.

Kitchen cabinet interior angles add up to 360 degrees
Dishwasher door four vertices or corners
Car window four sides (or 'edges')
every angle is a right angle opposite sides are parallel
all sides have equal length opposite angles are equal
Opposites sides are parallel and equal in length picture
