How many 1 in x 1 in x 1 in cubes will fit in the following prism?
Have students discuss their solution with a partner.
How many 1 in x 1 in x 1 in cubes would fit across the bottom of the rectangular prism?
How did you determine this number?
abright@pdx.edu

Example 1 (5 minutes)
How many cubes could we fit across the length? The width? The height?

3. A toy company is packaging its toys to be shipped. Some of the very small toys are placed inside a cube shaped box with side lengths of ½ in. These smaller boxes are then packed into a shipping box with dimensions of 12 in x 4 ½ in x 3 ½ in.
a. How many small toys can be packed into the larger box for shipping?

Here’s a re-wording:
Original
A toy company is packaging its toys to be shipped. Some of the very small toys are placed inside a cube shaped box with side lengths of ½ in. These smaller boxes are then packed into a shipping box with dimensions of 12 in x 4 ½ in x 3 ½ in.
How many small toys can be packed into the larger box for shipping?
Scaffolded
A toy company puts small toys into boxes. The boxes are cubes with side length of ½ in.
These small boxes are put inside a bigger box with dimensions of 12 in. x 4 ½ in. x 3 ½ in.
How many toys can be put into the larger box?

Another note on this lesson
These relationships between these words need to be taught!
abright@pdx.edu
How can teachers scaffold this curriculum?
abright@pdx.edu
Three* big ideas:
*More big ideas at the end!
abright@pdx.edu
Reduce the language load

A Standard Example (Lesson 8.1, p. 12)
Suppose a colony of bacteria doubles in size every 8 hours for a few days under tight laboratory conditions. If the initial size is 𝐵, what is the size of the colony after 2 days?
�
A Modified Example
A group of objects doubles every 8 hours.
Today there are B objects in the group.
How many objects are in the group after 2 days?
(There are 24 hours in one day.)

A Standard Example (Lesson 8.1, p. 12)
A rectangular area of land is being sold off in smaller pieces. The total area of the land is 𝟐𝟏𝟓 square miles. The pieces being sold are 𝟖𝟑 square miles in size. How many smaller pieces of land can be sold at the stated size? Compute the actual number of pieces.
�
�
Modified Example
Kim has a farm in the shape of a rectangle.
The area of Kim’s farm is 𝟐𝟏𝟓 square miles.
Kim divides her farm into pieces that are each 𝟖𝟑 square miles in size.
How many pieces does Kim make?
abright@pdx.edu
Provide side-by-side texts.
abright@pdx.edu
abright@pdx.edu
Provide step-by-step instructions in student-friendly language & use visuals.
Directions:�a) Define a variable for each problem.
b) Write an equation to represent the information.
c) Be sure the equation requires the use of one inverse operation to find the solution!
d) Show a check for each solution.

3. Provide support for speaking and writing
abright@pdx.edu
Give concrete guidelines for speaking, reading, writing or listening.
“Turn to your neighbor and explain…”
Write the day’s objective on the board and have students read it along with you. Point to each word as you read aloud.
Provide sentence frames for anyone who may benefit.
(“I know the area of parallelogram B is larger/ smaller ______ than the area of parallelogram A because _____.”)
(More advanced students might be ready for some transition language like this: http://writing2.richmond.edu/writing/wweb/trans1.http://writing2.richmond.edu/writing/wweb/trans1.html)
abright@pdx.edu
Sentence frames (perhaps with word banks) can support student explanations.
abright@pdx.edu
abright@pdx.edu
Word bank:
Added
Less than one
Combined
Whole number
Equal
abright@pdx.edu
Have students chorally repeat key vocabulary or phrases.
abright@pdx.edu

abright@pdx.edu
Other rich ideas
abright@pdx.edu
Use manipulatives!
abright@pdx.edu

Final things to keep in mind
abright@pdx.edu
Mathematics is not a universal language
abright@pdx.edu
Fractions may be �especially challenging
abright@pdx.edu
We can’t assume literacy in L1.
abright@pdx.edu
Students learn casual language before academic language.
abright@pdx.edu
Communicating in a new language can be very stressful.
