To Parents and Adults at Home …
During the next three weeks, your child’s class will be exploring geometry.
Through daily activities, your child will explore the relationship between flat,
two-dimensional figures and solid, three-dimensional objects in the world
around them.
In this unit, your child will:
 Construct congruent figures.
 Explore angles.
 Recognize and identify horizontal, vertical, perpendicular, intersecting,
and parallel lines.
 Sort and classify figures.
 Explore solids.
 Build nets.
Geometry is an important part of a student’s mathematical experience.
Geometry provides students with a strong link between the mathematics they
learn in the classroom and the real world.
Here are some suggestions for activities to do at home.
Look around the kitchen for different objects that have the same shape as a
solid. For example, a can of soup is a cylinder, a cereal box is a rectangular
prism, and an orange is a sphere.
Find objects that have the same shape, but have different sizes. For example,
drinking glasses often have the same shape, but come in different sizes.

LESSON 8A: Exploring Nets of Solids
EXPLORE
You will need a cereal box or a Toblerone box and a pair of scissors.






Cut along the edges of the box until you can lay it flat.
Place the flattened box on a large piece of paper.
Trace the box and cut out the tracing.
Use a ruler to draw the fold lines on the tracing.
Write about the figures you see.
Fold the tracing along the fold lines.
Show and Share
Share your tracing with another pair of students.
How are your tracings the same?
How are they different?
CONNECT
A cutout that we can fold to form a model of a solid is called a net.
We can make a net for a solid from its faces.
The faces must be arranged so that they can be folded to make the solid.
There are different ways to arrange the faces to make a net.
This rectangular prism has 2 congruent square faces and 4 congruent
rectangular faces.
Here are the steps to make a net for this prism.
 Trace around a
square face
2 times.

 Tape a square to
each end of one
rectangle.
 To check that this

Additional Activity 1:
Look Out for Angles
Work with a partner.
You will need old magazines, scissors, glue, a card with a square corner,
and heavy paper.
 Look for angles in the magazines.
Cut out each angle.
 Use the card to measure the angles as less than, equal to,
or greater than a right angle.
 Sort the angles by these attributes:
• Has all angles less than a right angle.
• Has all right angles.
• Has all angles greater than a right angle.
 Glue the angles on heavy paper to make an angle collage.
Take It Further: Draw a picture. Include items with right angles, angles less
than a right angle, and angles greater than a right angle.

Additional Activity 2:
Congruent Figures
Work with a partner.
You will need a ruler, triangular or square grid paper, scissors, glue,
and heavy paper.
 Draw 10 four-sided figures each.
 Write your initials on each figure.
 Cut out each figure.
 Place your figures and your partner’s figures on a table.
Look for congruent figures.
 If you find no congruent figures, choose one figure and draw a figure
congruent to it on grid paper.
 Glue each pair of congruent figures on heavy paper.
Write how you know the figures in each pair are congruent.
Take It Further: Repeat the activity. Draw figures that are not
four-sided figures.

Additional Activity 3:
Go Fish for Faces
Play with a partner.
You will need 36 Face-Off game cards (Master 3.12) and models of solids.
Each card shows the face of a solid.
The goal is to use all your cards to make solids.
How to play:
1. Decide who will be the dealer.
The dealer deals 6 cards to each player.
Players do not show their cards.
The deck of remaining cards is placed face down.
2. Players take turns. Player A looks at his cards.
If the cards show the faces of a solid, he places the cards face up and
says the name of the solid.
3. If Player A cannot make a solid with his cards, he asks Player B for a card
he needs to complete a solid.
If Player B has this card, she gives it to Player A.
If Player B does not have this card, she tells Player A to “go fish.”
Player A takes a card from the deck.
4. Player B has a turn.
5. Play continues until one player has no cards left or until all the cards have
been used.
The first player to use all his cards, or the player with the fewer cards left
when all the cards have been used, is the winner.
Take It Further: Play the game again. Add cards that show different faces,
such as hexagons and pentagons.
