Title: Supported Mathing
1Supported Math(ing)
- Using AT in the Mathematics Process
2Consider this...
- You went to the ATM machine and it would not give
you 200 to buy groceries and fill your
prescription refill because you had insufficient
funds. You balanced your checkbook 2 weeks ago. - How much money can you get from the ATM?
3Consider this...
- You need to clock-in at work at 400 at the
Burger King in the food court at the mall. You
take the bus to work. The bus stop is one block
from your apartment and the bus lets you out at
the opposite side of the mall from the food
court. - When do you need to leave your apartment?
4To solve these problems...
- What information do you need to have?
- What do you need to do with this information?
5To solve it....
- What
- Process?
- Equation or formula?
- Estimation?
- Calculation?
- did you use?
6Math(ing)
- Purpose
- To determine how much or how many
- To determine when or how soon
- Outcomes
- Measure (objects, time, amount, distance)
- Compute (totals, differences, values)
- Solve complex problems
7Math(ing)
- Skills (Functions)
- Computing / Calculating / Measuring
- Exact amounts
- Estimates (e.g., nearest dollar strategy
- Process (Analyzing)
- Determine what type outcome is needed
- Select a formula (a math sentence)
- Fill in the values
- Determine the solution
8Math(ing)
- Writing Math
- Why do we need to write math?
- What does writing math involve?
- What are AT tools for writing math?

10AT for Math(ing)
- The purpose of AT is compensatory
- Therefore, the tools needed are those that
- Enhance or replace the skills
- Needed to produce math outcomes
- What AT tools do you use, know or have already
seen in class?
11AT for Math(ing)
- Tools for measuring
- What do we measure?
- Length or distance
- Elapsed time
- Amounts (number or volume)
- What are the barriers to measuring?
- What are the perceptual or physical barriers
- What are the cognitive barriers?
- What are the AT tools?
12AT for Math(ing)
- Tools for computing
- What do we compute?
- Totals
- Differences
- Proportions / percentages (e.g., tips)
- What are the barriers to computing?
- What are the perceptual or physical barriers
- What are the AT tools?
13What are the cognitive barriers to computing?
- Recall of
- Number names and number values
- 1 one / one one
- 3 ? ? ?
- Math operators - /
- Number facts
- Addition tables
- Equivalences
- Money equivalence (e.g., making change)
- In ft, tsp T, oz cup
- Computational rules
- Borrowing, carrying
- Fractions
What are the AT Tools?
14What are the cognitive barriers to computing?
- Knowledge of
- Math logic basic processes
- One to one correspondence
- Math operations (add, subtract, multiply, divide)
- Math linguistics (e.g., spoken or printed
words) - Add, and, subtract, take away, more,
- Greater than / less than
What are the AT Tools?
15AT Supported Math Strategies
- Many of the AT math tools are a combination of
- The tool (e.g., a calculator)
- AND
- A strategy
- Put 10.00 on the calculator
- Get items from the shopping list
- Subtract each items price as you put it in the
cart - Stop getting items when it says 0.00
- If the number starts with a - put the last item
back
16The Computer as a Tool in Mathematics
- Most common tool software is the word processor.
- Other popular tools include spreadsheets,
databases, and PowerPoint. - Electronic Manipulatives for Numeration (applets
and software)

21Math
- Computer software can be a good tool to reinforce
basic mathematical skills. - However, most programs are skill-and-drill
programs that are marketed to the general school
population.
22- As for students with disabilities, few research
studies have been done on the impact of computer
use on the understanding of mathematics
principles. - Good software.
23Manipulatives (physical models)
- Unifix cubes
- Cuisenaire Rods
- Counters (examples plastic tiles, chips, bears)
- Ruler, tape measure
- Clocks (analog, digital)
- Abacus
- Calculator
24Unifix Cubes
25Talking Tape Measure
26Calculators contribute to the learning of
mathematics
- Benefits
- Helps to develop concepts
- Use for practice or drill
- Enhances problem solving
- Improves student attitudes
- Saves time
- Seen as a commonplace tool in society
27Talking Calculator
28- Flexible plastic ruler allows tactual visual
measurement raised lines in ¼ increments white
w/ raised black lines w/ numbers in Braille
large print.
- 18-inch flexible Braille/large print ruler.
