Improving Access to Mathematics: Strategies for Intermediate Students
Presented byHeather Sparks, NBCT2009 Oklahoma Teacher of the Year
What makes math difficult?
Lack of prior knowledge Missing foundational skills Limited experiences with “doing”
math “One right answer” approach “Permission” to be “bad” at math Others?
STRATEGIES:1. Constant exposure to meaningful math
Every day, provide meaningful math investigations through manipulatives, games, puzzles, and stories.
Content example: True Blue Love Box Company
True Blue
Trina wants to win a goldfish at the carnival. In order for her to win, she needs to pick 2 blue tiles out of the “True Blue prize bag,” without looking. If the prize bag contains 3 blue tiles and 3 red tiles, what is the probability of winning the game?
Predict the number of wins you willget in 40 trials. Then, conduct the trialsand record the outcomes.
Love Box Company
Love Box Company wants to create a box that holds 12 cubic inches. Each square inch of cardboard costs the company $.005. What are the dimensions of the least expensive box the company can create?
STRATEGIES:2. Allow students to verbalize their thinking
Every day, expect students to explain theirthinking.
Content example: Sense & Nonsense Farmer John
Sense & Nonsense
1. Mr. Bragg says he’s right 100% of the time. Is he bragging? Why?
2. The Garcia family ate out last Saturday. The bill was $46. Would a 50% tip be too much to leave? Why?
3. Ellen loaned Me’Shell one dollar. She said the interest would be 75% a day. Is this a pretty good deal for Ellen? Why?
4. Daniel missed 10 problems on his science test. Do you think his percentage is high enough for an A? Why?
5. Rose has a paper route. She gets to keep 25% of whatever money she collects. Do you think this is a good deal? Why?
Farmer John
Before planting the Spring crops, Farmer John needs to determine how many acres will be allocated for his vegetables. He decides to plant 5% of the area with onions, 20% with tomatoes, 25% with egg plant, 25% with corn, and 25% with carrots. The number of acres for each crop must be whole numbers. Help John determine the minimum number of acres that will be planted and the acreage allotted to each vegetable.
Onions= tan Corn= yellowTomatoes = red Carrots= orangeEgg plant = purple
John must also consider that different plants have different space requirements. Use the rods to represent the required space as follow:
STRATEGIES:3. Provide for meaningful use of manipulatives
Manipulatives should be available and integrated into relevant math lessons.
Content example: Squares & Staircases Extend & Explain
STRATEGIES:4. Help students develop “bridge” tools
Students should be taught specific strategies to improve memory and understanding
Content example: Order of Operations Chant Integer Song
Order of Operations Cup Chant
Paren- theses clap clap
Ex- po- nents tap tap tap (the top of the cup)
Multi ply, Divide clap grab cup’s bottom, pick up and move cup right
Add, Subtract clap grab cup with thumb side down
Left to right,Bring open mouth of cup to left hand touch bottom of cup to table
Order’sTransfer cup to left hand by grabbing the bottom of the cup
on your side!Right hand slaps table Left hand crosses over & puts cup down
(Tune: Row, Row, Row Your Boat)
Same signs, add and keepDifferent signs, subtractKeep the sign of the larger numberThen you’ll be exact!
Integer Song
STRATEGIES:5. Create “reference” resources
Students should maintain a math journal to record and store math resources.
