The document summarizes lessons from a workshop on the Singapore Math approach held at St Edward's School in Florida. It provides an overview of the Singapore education system and curriculum. It then summarizes 5 lessons that were observed which demonstrate the Singapore Math approach of using visual models and thinking strategies to teach basic math concepts and solve word problems. The lessons focused on multiplication facts, bar modeling techniques, and differentiated instruction strategies to help struggling students.

16. Lesson 1
We did a lesson on multiplication facts to understand the
emphasis on visualization in learning basic materials. We also
saw the use of an anchor tasks to engage students for an
extended period of time.
17. Lesson 1 June 18, 2012
Problem
2x4=8
10 x 4 = 5 x 4 = 20
5 x 4 = 20
9x4=
2x4=8
4x4=
8x8=
7x4=
2x4=8 6x4=
5 x 4 = 20 3x4=
2x4=8
This Grade 2 lesson on multiplication facts of 4 centers around using doubling
strategy and adding one row strategy in addition to previewing more advanced
strategies such as using 2 x 4 and 5 x 4 to get 7 x 4 as well as ‘subtraction’ strategy.
The anchor task is to use 2 x 4 and 5 x 4 to obtain all the other facts. The anchor task
allows students to work on one task for an extended period of time.
21. Lesson 2
We continued to see the emphasis on visualization through the
use of bar models in solving word problems. This lesson was
done with a small group of Grade 3 students who have no
experience with Singapore Math. This session and the ones
after lunch focused on helping students who have difficulties
with reading word problems, representing complex situations
and doing computations. We also saw the use of the cut up
word problems in doing differentiated instruction.

25. Lesson 2 June 18, 2012
Story 2
Kyla had $3 more than Jack. Who had
more money
Jack $2 afterwards?
How much
Kyla $3 more?
Jack gave Kyla $2.
26. Kyla had $3 more than Jack.
Jack gave Kyla $2.
How much more did Kyla have than Jack?
Students in Grade 6 may use algebra to deal with Story 2.
Kyla had $(x + 3)
Jack had $x
Then, Jack had $(x – 2)
And Kyla had $(x + 5)
Kyla had $(x + 5) – $(x – 2) or $7 more than Jack.
27. Lesson 3
Question: How do we help students set up the model? Students
are introduced to the idea of using a rectangle to represent
quantities – known and unknown. Paper strips are used. Later,
only diagrams are used. Advanced skills like cutting and
moving are learned in Grades 4, 5 and 6. How is the idea of bar
model introduced in Grades K – 3? Listen out for this on Day 2.
Lesson 3 show a basic bar model solution.
30. 2x + x = 4686
3x = 4686
Students in Grade 7 may use algebra to deal with such situations. Bar
model is actual linear equations in pictorial form.
31. Lessons 4 & 5
We studied the strategies to help struggling readers as well as
those weak in representing problem situations.
• Who is in the story? What is it all about?
• Is the sentence easy?
• Read a complex sentence as simple sentences.
• Leave out numbers in reading
