Estimating Length in Metric Units

Here is a quote from the book we read in class today, Millions to Measure, by
David Schwartz:
“Many people believe that the United States will eventually join the rest of the
world and measure only in the metric system.”
Do you think this is a good idea or not? Please explain your answer.

NOTE TO FAMILIES
We are studying double-digit multiplication in class. One way to solve a problem like 24 × 37 is to think
of it as 4 smaller multiplication problems: 20 × 30, 20 × 7, 4 × 30, and 4 × 7. When you break it down
this way, you can see that it helps to be able to multiply single and double-digit numbers by 10 and
multiples of 10, like 20, 30, and 40. Multiplication Four in a Row and the related worksheet will help students practice this skill.
You’ll need a partner and 2 small markers, such as paperclips or pennies, to play
this game.
Instructions for Multiplication Four in a Row
1
Play Rock, Paper, Scissors or flip a
coin to decide who will go first.
2
Put the markers on top of 2 of the
multipliers in the row above the game
grid. You can choose 2 different multipliers, like 20 and 40, or put the markers on the same multiplier, like 30 and
30. Then multiply the 2 numbers and
write an x over the answer on the grid.

Home Connection 13 H Worksheet
NOTE TO FAMILIES
One way to think of a multiplication problem like 13 × 15 is to picture it in the form of a rectangle. We
have been doing this a lot in class recently. When you do this, the two numbers you’re multiplying are
the dimensions of the rectangle, and the area of the rectangle is the answer. The advantage of looking at
it this way is that you can actually see the pieces or “partial products” that make up the total. This Home
Connection provides more practice using this area model to solve double-digit multiplication problems.

Looking for Metric Measures at Home
In his book, Millions to Measure, David Schwartz writes, “Even though the metric
system has not been adopted by people in the United States, many Americans
use it every day.” Today’s Home Connection will give you a chance to check this

Containers that hold liquids like juice, soda pop, shampoo, or liquid soap may be

NOTE TO FAMILIES
Over the past two weeks, we have been using many different strategies to multiply larger numbers, some
of which are shown below. In this homework assignment, students should try to use more than one of
these strategies, but they should always do what makes the most sense to them. Students may have
their own variations on the strategies and may write them in different ways than those shown below.
Multiplication Strategies
Review the multiplication strategies on this page. Then solve the problems on the
following pages. Use a few of these strategies to solve the problems. Choose the
strategies you use based on what makes the most sense for the numbers in the
problem. Don’t use a strategy unless it makes sense to you.
Use a Basic Fact Strategy
Strategies for the basic facts can be used with larger numbers too.
example
Use the half-decade strategy to multiply by 5.
86 × 5 = (86 × 10) ÷ 2 = 860 ÷ 2 = 430
Break One of the Numbers into Parts and Then Multiply and Add
Especially when the digits are small, you can break one of the numbers into tens
and ones, multiply by the other number, and add the two products.
example
21 × 32 = 21 × 30 + 21 × 2 = 630 + 42 = 672
Use a Sketch of the Area Model (a Rectangular Array)
You can make a quick sketch of an array to show the multiplication problem and
then solve it. You can divide the array into as many parts as you like to compute
the total product.
example

10 × 20 = 200

Use an Algorithm
An algorithm is a step-by-step procedure for solving a problem. Algorithms can
be the most sensible way to solve some problems, especially when the numbers
are very large. We have talked about the two algorithms shown below in class.
In the one at left, all the multiplication is done before the addition. In the one at
right, we alternate between multiplying and adding.

NOTE TO FAMILIES
One way to solve a long division problem is to picture it in the form of a rectangle. When you do this,
the number you’re dividing by is one of the dimensions and the number being divided is the area of
the rectangle. Quotients Win will help students practice using this strategy to sketch and solve such
problems as 150 ÷ 10 and 220 ÷ 22. Your fifth grader can show you how to make the sketches, and

160 ÷ 10. First I’ll show 10 on the
side and then start filling in the
array until I get to 160. My rectangle
turned out to be 16 along the other
side, so that’s the answer.

Make a labeled sketch of the problem on the game sheet and fill in the

2
Choose any 3-digit number that is
less than or equal to 900. Enter it into
the calculator and then give the calculator to your partner.
3
Player 2 uses the calculator to reduce the number to 0 by adding, subtracting, multiplying, or dividing by
single-digit numbers other than zero. You
can make as many as 5 calculations
(but no more) to get the original number down to zero. Do your work on the
calculator, but record each move on
the record sheet.
4
Play back and forth until you have
each had 3 turns. Then count up the
total number of calculations you made
and use the more or less spinner to
determine the winner. If the spinner
lands on “more,” the player who made
more calculations wins. If the spinner
lands on “less,” the player who made
fewer calculations wins.
example
Player 1 chooses 334.
Player 2:
• divides 334 by 2 to get 167 (calculation 1)
• subtracts 7 from 167 to get 160 (calculation 2)
• divides 160 by 8 to get 20 (calculation 3)
• divides 20 by 4 to get 5 (calculation 4)
• subtracts 5 from 5 to get 0 (calculation 5)
Starting Number (Chosen by Player 1)
Calculation 1
334 ÷ 2 = 167
Calculation 2
167 – 7 = 160

Area & Perimeter
Perimeter is the distance all the way around the rectangle. It is measured in linear
units (centimeters, in this case).
Area is the number of square centimeters it takes to cover the shape.
Measure and then label the length and width of each rectangle in centimeters. If
you don’t have a centimeter ruler at home, cut out the one on page 73 and use it
instead. Find the area and perimeter of each rectangle using the most efficient
method you can. Show your work.
example
4 cm
Perimeter = 12 cm
Work: 2 + 2 + 4 + 4 = 12 cm

Area = 8 sq. cm
