5. Math Facts about Bahrain
Bahrain is actually an archipelago of 33 islands.
The largest, on which many people live, is 55km
long by 18km wide and areas such as Sitra and
Muharraq are actually separate islands.
Bahrain’s flag used to be the largest flag in the world,
setting a Guinness world record in 2004 at 169.5m long
and 97.1m wide. The five red points signify the five pillars
of Islam. The oldest known Bahraini flags were plain red.
In 1820, the island signed a treaty with the UK and a white
stripe was added to the flag to indicate the truce. In 1932,
a serrated edge was added to distinguish Bahrain’s flag
from those of its neighbours. The flag originally had 28
white points, but this was reduced to eight in 1972 and
five in 2002.

6. More Math Connections in Bahrain
Bahrain World Trade Centre is the first skyscraper in
the world to integrate wind turbines into its design.
Each turbine is 29m in diameter and their capacity is
675kw of wind power production. The 240m-tall tower
has won several international awards including the
LEAF (Leading European Architects’ Forum) award for
best use of technology in a large scheme.
The British School of Bahrain holds the world record
for the largest simultaneous coin toss. As part of
World Maths Day in 2010, 1,117 staff and students
took part in the toss which made it into the Guinness
Book of Records.
7. Why use manipulatives?
Concrete.
The “doing” stage using
concrete objects to model
problems
Representational.
The “seeing” stage using
representations of the objects
to model problems
Abstract.
The “symbolic” stage using
abstract symbols to model
problems
8. Solving Basic Facts: Partner Work
The Student’s Hat
Work on the problems, using
manipulatives to concretely
model the solution.
The Teacher’s Hat
Consider student abilities:
Direct modeling,
counting, derived
facts, recall
PROBLEMS
5 + 7 = ?
12 – 5 = ?
4 + ? = 11
5 x 7 = ?
56 8 = ?
9. PROBLEM DIRECT MODELING COUNTING DERIVED FACTS RECALL
5 + 7 = ?
Join Result
Unknown
Makes a set of 5 counters and a set
of 7 counters. Pushes the two sets
together and counts all the
counters.
Counts “5 [pause], 6, 7, 8, 9, 10, 11,
12,” extending a finger with each
count. “The answer is 12” [The
counting sequence may also begin
with the larger number]
“Take 1 from the 7 and give it
to the 5. That makes 6 + 6,
and that’s 12.”
5 plus 7 is 12.
12 – 5 = ?
Separate Result
Unknown
Makes a set of 12 counters and
removes 5 of them. Then counts
the remaining counters.
Counts back “12, 11, 10, 9, 8
[pause], 7. It’s 7.” Uses fingers to
keep track of the numbers of steps
in the counting sequence.
“12 take away 2 is 10, and
take away 3 more is 7.”
12 take away 5 is 7.
4 + ? = 11
Join Change
Unknown
Makes a set of 4 counters. Makes a
second set of counters, counting
“5, 6, 7, 8, 9, 10, 11,” until there is
a total of 11 counters. Counts the
7 counters in the second set.
Counts “4 [pause], 5, 6, 7, 8, 9, 10,
11,” extending a finger with each
count. Counts the 7 extended
fingers. “It’s 7.”
“4 + 6 is 10 and 1 more is 11.
So it’s 7.”
4 and 7 make 11.
5 x 7 = ?
Makes 5 groups of 7 counters and
counts them all.
7, 14, 21, 28, 35 or
5, 10, 15, 20, 25, 30, 35
5 times 5 is 25 and 10 more
is 35.
5 times 7 is 35.
56 8 = ?
Counts out 56 counters. Pulls out
groups of 8 until 7 groups are
made.
8, 16, 24, 32, 40, 48, 56 8 times 8 is 64. 8 less is 56.
So that’s 7.
8 x 7 is 56.

10. Create a Mini-Lesson
Components for the Mini-Lesson
• at least one math manipulative
• CCSS-M (math standard)
• Standard(s) for Mathematical Practice
• Interdisciplinary connection/s
• Independent/pair/small group/whole
group?
• How will students communicate
mathematically?
Manipulatives for
Consideration
• Counters
• Connecting cubes
• Base ten counters
• Number line
• Random number generator
(number cubes)
• Spinners
11. 1. Make sense of problems and
persevere in solving them.
2. Reason abstractly and
quantitatively.
3. Construct viable arguments and
critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of
structure.
8. Look for and express regularity in
repeated reasoning.
Learning through the
Standards for Mathematical Practice
12. “The difficulty with fractions (including decimals and
percents) is pervasive and is a major obstacle to
further progress in mathematics. . .”
—Report of the National Math Panel, March 2008
Fraction Sense
13. What are some of the biggest challenges
students face with fractions?
14. In One Minute…
• write down everything that comes to mind when you think about or see

15. Now, in one minute…
• write down everything that comes to mind when you think about or see

16. Compare Your Responses
• What similarities do you see?
• What differences do you see?
• Any surprises or insights?
19. Develop understanding of fractions
• 3.NF1 Understand a fraction 1/b as a quantity formed by 1 part
when a whole is portioned into b equal parts: understand a
fraction a/b as the quantity formed by a parts of size 1/b.
20. TASK:
Locate 1 on the number line. Label the point.
Be exact as possible.
While it is not necessary to name all of the intervals on the number line, many students
may do so .

22. Other Helpful Considerations for Understanding
Fractions
• Where do we see and use fractions
in our daily lives?
• Support Strategy: The use of
pictures provides students with
realia for understanding
fractions
• Wholes vs. Holes
• Use visual images that support
all learners for understanding
this concept.
• Fraction Basic Vocabulary (denominator)
• 2 is pronounced “half”
• 3 is pronounced “third”
• 4 is pronounced “fourth” (or “quarter”)
• 5 is pronounced “fifth”
• 6 is pronounced “sixth”
• 7 is pronounced “seventh”
• 8 is pronounced “eighth”
• 9 is pronounced “ninth”
• 10 is pronounced “tenth,” and so on.
23. Equivalent Fractions
• The meaning of fraction equivalence
• The equivalence of whole numbers and fractions
• Explaining fraction equivalence in general
24. Adjectives vs. Nouns
(Adapted from Kathy Richardson, NCTM 2008)
• Young children initially consider numbers as adjectives or descriptors
• 9 bears
• 6 cookies
• 20 students
• Eventually, they come to understand numbers as nouns or concepts
9 is …
• half of 18,
• It is 1 less than 10,
• It is 4.5 doubled,
• It is 3 squared,
• It is the square root of 81,
• ………..?
25. Adjectives vs. nouns (continued)
• Students need opportunities to transition from considering fractions as adjectives
1/2 of a pizza
3/4 of an hour
2/3 of a cup
• to considering them as nouns
5/8 is…
a little more than 1/2, but less than 1
It is 3/8 less than 1
It is equivalent to 10/16
It is twice 5/16
It is half of 1¼
