Math 300: Mathematics Concepts for Teachers, Spring 2016

Reading and Homework Assignments

Week 1

HOMEWORK #1: Due Wednesday, January 27th:

 

Homework Assignment:

·       Consider the following word problem:

Four toy cars cost as much as 3 dolls. Five toy cars cost $3.50 more than 2 dolls. Allison spent $14 on an equal number of toy cars and dolls. How many toy cars did she buy?

 

--Work on coming up with a solution to the problem individually for 10 minutes.

--Get into a group of 3-4 to discuss the problem and come up with at least two different ways of solving it and showing it.  Be sure that one of your strategies does not use algebra.

--Videotape your favorite solution.  Try to be creative.  Email me a link to your presentation (please be sure that it is no longer than 5 minutes and that each person in the group has the opportunity to speak) before midnight Tuesday, January 26, 2016.

--We will view and discuss the presentations on Wednesday.

HOMEWORK #2: Due Monday, February 1st (on the desk in our classroom, before class begins):

·       Solve each of the following story problems in two ways:

o   Algebraically

o   Using the model method

 

1.    Four toy cars cost as much as 3 dolls. Five toy cars cost $3.50 more than 2 dolls. Allison spent $14 on an equal number of toy cars and dolls. How many toy cars did she buy?

2.    Paige and Cody collected a total of 160kg of acorns.  Cody collected 3 times as many kg of acorns as Paige.  How many kg of acorns did Cody collect?

3.    Angela bought a roll of ribbon.  After using 5/8 of the ribbon to tie some packages, she had 15m of ribbon left.  How many meters of ribbon did she buy?

4.    Hannah cut 1/2 ft pieces of string from a string 1 3/4 ft long? How many 1/2 ft pieces of string did Hannah have when she was done cutting?  (Include fractional pieces of string.)

5.    Marissa has some ice cream.  4/7 of her total amount of ice cream is vanilla ice cream.  If Marissa has 1 1/3 gallons of vanilla ice cream, how much ice cream does she have altogether?

6.    Megan spent $2 1/2 on 3 1/3 yards of fabric to make a quilt.  How much fabric can be purchased for $1?

 

Makes sure that you:

·       Define the variables.

·       Restate the problem in your own words.

·       Give the solution, step by step.

·       State the answer in a complete sentence.

 

Each pair of students:

·       Select one of the word problems above and create a video with the two different strategies—algebraic and using the model method.

1.    Be creative to help the viewer understand.

2.    Make sure each person has an opportunity to speak.

3.    Send me a link to your video by midnight, Monday, January 31st. 

 

Each video should be approximately 3-5 minutes in length (no longer).
