Mathematics

Emerging Agreements· Mathematical fluency requires automatic

recall of certain procedures and algorithms.

· Use of calculators in instruction can be useful but must not impede the development of fluency with computational procedures and basic facts.

· Using and understanding the basic algorithms of whole number arithmetic is essential.

Emerging Agreements (cont’d)Developing an understanding of the number

meaning of fractions is essential. Teachers must ensure that the use of “real-world”

contexts for teaching mathematics maintains a focus on mathematical ideas.

Mathematics should be taught using multiple strategies,

Mathematics teachers must understand the underlying meaning and justifications for ideas and be able to make connections among topics.

(Ball, Ferrini-Mundy, Kilpatrick, Milgram, Schmid, & Scharr, 2005).

Best PracticeStudents’ engagement is at a high level. Tasks are built on students’ prior knowledge. Scaffolding takes place, making connections to

concepts, procedures, and understanding. High-level performance is modeled. Students are expected to explain thinking and

meaning. Students self-monitor their progress. Appropriate amount of time is devoted to

tasks.

Recommended PracticesEnsure mathematics curriculum is

based on challenging content, Ensure curriculum is standards basedClearly identify skills, concepts and

knowledge to be mastered, Ensure that the mathematics

curriculum is vertically and horizontally articulated.

IBPYP Requirements for MathTransdisciplinary- strong

connections with UOIs,Math Inquiry- Inquiry based

learning environment,Move away from a text-based math

program, create standalone units for math strands where strong connections can’t be made with the UOI.

Time to Think!!!

Number Strategies Addition

There are 47 children in the hall. 28 more children arrive. How many are in the school hall now?

Solution 47 + 28 =How did you work it out?What happened in your head?

Share your different strategies with the people around you.

Can you think of any other ways to solve the problem?

Make sense of these Strategies“Four rows of ten is 40 and two rows of ten is 20, so 40 + 20 = 60 with 7 and 8 left ! double 7 = 14 plus 1 =15

so there are 75 children”

“I use tidy numbers:

50 + 28 = 7878 - 3 = 75”.

“I know that 50 plus 30 is 80 and 3 plus 2 is 5,

so 80 - 5 is 75 “

“I think of 47+28

7 plus 8 is 15, so that’s 5 and carry one. 4

plus 2 is 6 plus one more ten is 7. so the answer

is 75”

“I use an open number line!”

Number Strategies Multiplication

There are 4 packets of biscuits with24 cookies in each pack. How many cookies are therealtogether?

Solution 4 x 24 =How did you work it out?What happened in your head?

Share your different strategies with the people around you.

How else could this problem be solved?

Make sense of these Strategies.

“I used place value 4 x 20 =

80.And 4 x 4 = 16.80 + 16 = 96

I used doubling and halving.

Double 4 = 8, half 24 = 12.8 x 12 = 96

“I think of 24 X4

4 x 4 = 16. Put down the 6 and

carry the 1.4 x 2 = 80 + another ten =

9090+6 = 96

4 x 24 =

“I use tidy numbers:I know 4 x 25 = 100.

100-(1x4) = 96.

“I know 24 + 24 = 48.

48 + 48 = 96

Class Example

Goals Developing multiple flexible thinking

strategiesMental and oral before written

standard vertical formsMake decisions about the most

efficient strategy to use on any given problem.

Challenge children to achieve and develop a positive attitude towards learning mathematics.
