## The Literature Connection

## Concepts Covered:

## Sunshine State Standards:

MA.3.A.2.2

MA.3.A.6.2

MA.4.A.2.3

MA.4.A.6.3

MA.6.A.2.2

MA.6.A.5.1

MA.7.P.7.2

## Materials for each group:

1 box of markers

1 paper lunch bag with candy

10 sticky labels

assorted packs of sticky notes

1 calculator

grid/chart paper

Student Arrangement:

## Procedure:

## Day 1: Table

*Cucumber Soup *by Vickie Leigh Krudwig to students.

How did you construct and organize your models of the insects?

Why did you arrange them that way?

What are other methods we could use to organize this information?

## Day 2: Multiples

How many bugs are there in all?

What would happen to the number of bugs if 2 or more cucumbers fell
on the anthill?

How many of each bug would be needed to move the cucumbers? (Fill in
table)

What patterns do you see?

What kinds of numbers are these?## Day 3: Fractions

Show each bug’s
fractional representation of whole bug group on chart paper.

Discuss need to simplify some of the fractions.

**Day 4: Ratio Part to Whole**

Ex. There are 9 mosquitoes for every group of 55 bugs. State this comparison
as 9 to 55. Explain this is called a ratio. It can be written in several
ways. In words, it can be written as "9 to 55". We also have
a symbol to replace the word "to." Ask if anyone already knows
this symbol. Show an example of a ratio using the colon (9:55).

What about the fractions we simplified?

What happened to their ratio?

What about the equivalent fractions we calculated earlier?

Will their ratio be any different than the ones we just completed? Why?

## Day 5: Ratio Part to Part

Day 6: Probability

Which bug would a hungry robin eat if he swooped down on the mixed group
of bugs?

Why do you think that?

Is it guaranteed that the bird will really catch that bug?

Discuss terms used when talking about probability.

Discuss probability and its mathematical representation

Lead the group to discover the fractional representation, decimal, and
percent form - the probability of catching a mosquito is 9/55, or about
0.16, or about 16%. **Probability Activity/Game**

Pull apart snap cubes and place inside paper bag (Just the right number
of cubes for each bug group).

Predict bug/cube will be pulled from the bag.

Tell the group the
probability of getting that bug.

Students who successfully predict which bug is pulled may choose one
piece of candy

Return all cubes to the bag after each try.

This time, pick two bugs that you predict will be chosen

Pick one cube from
the bag.

Predict which bug is likely
to be chosen

Pick
two cubes from the bag.

## Discussion:

How do probability and ratio tie into fractions, decimals, and percent?
