Lesson 15: Converting Yards to
Centimeters
Since 1 yard =
0.914 meters, and 1 meter = 100 centimeters, 1 yard = 0.914
x 100 = 914 centimeters.
Exercise 15: Convert the following yards
to centimeters.
1
yard = 914 centimeters, 4 yards = _____________ centimeters.
5
yards = ____________ centimeters, 17
yards = _____________ centimeters.
8
yards = ____________ centimeters, 3
yards = _____________ centimeters.
9
yards = ____________ centimeters, 6
yards = _____________ centimeters.
7
yards = ____________ centimeters, 2
yards = _____________ centimeters.
Lesson 16: Converting Feet to Meters
Since 1 meter
= 3.282 feet, 1 foot = 1 /
3.282 meters = 0.3048 meters.
Exercise 16: Convert the following feet
to meters.
1
foot = 0.3048 meters, 4 feet = __________________ meters.
5
feet = _____________ meters, 17 feet =
__________________ meters.
8
feet = _____________ meters, 3 feet
= __________________ meters.
9
feet = _____________ meters, 6 feet
= __________________ meters.
7
feet = _____________ meters, 2 feet
= __________________ meters.
Lesson 6: Problem Solving Strategies
Using Models
Gina and her mom made 560 flowers in five days. Mom
made three times as many flowers as Gina made per day. How many flowers did
Gina make per day? How many flowers did Mom make per day?
What
we know: (1) Gina and her mom made 560 flowers in 5 days
(2) Her mom made 3
times as many as Gina.
What
to solve: (1) How many flowers did Gina make per day?
(2) How many flowers
did her mom make per day?
To
solve the questions, use the model below.
Gina
and her mom made 560 flowers in 5 days:
(1) Find the number of flowers
that
Gina and
her mom made per day.
112 flowers
They made 1/5 of 560 flowers per day.
560 
5 = 112 flowers
(2) Find the number of flowers
that
Gina
made per day.
Gina made ¼ of 112 flowers per day.
She made 112 (3 + 1) = 112 4 = 28 flowers per day.
(3) 
Find the number of flowers
that
her mom made per day.
Her mom made ¾ of 112 flowers per day.
She made 28 x 3 = 84 flowers per day.
Lesson 9: Basic Concepts of Equations
If
the whale box is 85 pounds and the octopus box is 85 pounds, the seesaw is
balanced. If
the whale box is 70 pounds and the octopus box is 50 pounds, the seesaw
will not be balanced. How
can you make the seesaw balance, if the whale box is 70 pounds and the
octopus box is 50 pounds?
An equation is
just like a balancing seesaw. Both sides of the equal sign must be the
same. 20
Add 20 pounds to the octopus’ side or
take away 20 pounds from the whale box to make it balance. 20
Let’s write an equation for the seesaw
above,
If the whale box is 70 pounds and the
octopus box is 50 pounds, we can
(1) add 20 pounds on the octopus
side:
Both sides are 70
pounds.
Whale Box = Octopus Box + X
Both sides
are 50 pounds.
70 pounds =
50 pounds + 20 pounds
(2) take away 20 pounds from the
whale box:
Whale Box –
X = Octopus Box
70 pounds
– 20 pounds = 50 pounds
