10Thinking About Measurement
- Would it make sense to measure the distance
between two cities with a yardstick? - How could you measure the circumference of
(distance around) the lid of a jar? - How would you measure the diameter of a ball?
- How would you estimate the height of a three
story building?
11Renaming Measurements
- Is 18 inches more or less than a foot?
- What fraction of 1 foot is 6 inches?
- 2 yards is equal to how many feet?
- 2 feet is equal to how many inches?
- Give another name for 2 feet 3 inches
- Give another name for 5 feet
12Independent Practice
Math Journal Page 246
- Practice measuring in centimeters and inches,
renaming measurements, and finding the areas of
rectangles. - Remember to begin measuring at the 0 mark.

These arrows are showing ___________________
- Bases of a Prism
- Remember that bases are any two pairs of
opposite faces. The bases are rectangular and
parallel and have the same area. - Height of a Prism
- The height of a prism is the distance between
the two opposite bases.
18Group Work
Math Journal Page 249 Part One Only
- Each student will need 10 cm cubes.
- We will break into groups of 4 students. Each
group will get a copy of math masters 166. Each
student is responsible for cutting out and taping
a rectangular prism (A, B, C, or D). - Discuss the prisms from your group and estimate
how many cubes you think it will take to fill
each of the rectangular prisms. -
- How will you find out how many cubes would fill
the prisms?
19Group Work Follow Up
Math Journal Page 249 Part One
- What do you notice about the cubes in the
rectangular prisms? - Is there an algorithm we could use to easily
find the number of cubes in a prism? - The number of cubes needed to fill a box is the
volume of the box. The algorithm for volume is - Area of Base X Height

Measuring Weight
What do we already know about weight? What units
of measurement can you list?
37Categorizing Units of Weight
38Examining Kinds of Scales
- Lets look at different types of scales found in
your SRB, on pages 147 and 148. - There are two things we need to know about
scales. - Capacity of a Scale
- the weight a scale can measure.
- Precision
- the size of the unit of measurement. The smaller
the unit the more precise the scale.
39Group Work Exploring Scales
- You will be working with a partner to complete
math journal page 255. - You will be brainstorming objects that can be
measured or weighed by the different scales that
are categorized. -
- When you have finished you may complete math
journal pages 256 and 257 independently. You will
be working with weight on these pages also.

many crayons altogether? - Answer________________________
- 9 tables with 4 children at each table. How many
children? - Answer ___________________________
- 300 pennies shared by 10 children. How many
pennies per child? - Answer __________________________
43Examining 4 Objects
- I will be displaying four objects. You need to
evaluate them and estimate the order of the items
by weight. - Use part one of math journal page 251.
- Then estimate and rank the order of items by
volume, using part two of the same page.
44Discussing your Estimates
- Take a minute to discuss your predictions with
your partner. - Why did you rank certain objects as heavier or
lighter? - How did you rank your volume? Explain your
thinking.
45Conducting the Volume Experiment
- We are going to test the volumes of our four
objects using containers and water. We will be
measuring how much water is displaced from the
container after each object is inserted. The more
water displaced, the greater the volume of the
object.
46Discussing the Experiment
- How you would explain the relationship you
noticed?
Can you name two objects for which the heavier of
the two also has a greater volume? Can you
name two objects for which the heavier of the two
has the smaller volume?
47Independent Work
- Complete the parentheses puzzles on the bottom
of page 251. Remember that the parentheses tell
you what operation to do first. -
- Complete the review math boxes on page 259 of
your math journal.

used to measure liquids.
51Capacity
- We have learned about the capacity of scales,
what they are able to weigh. Today we are
learning about the capacity of a container, how
much liquid it can hold. Measures of capacity are
special measures of volume.
