Lesson 1We 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.

Lesson 1 June 18, 2012
2 x 4 = 8
5 x 4 = 20Problem10 x 4 = 5 x 4 = 209 x 4 = 2 x 4 = 84 x 4 = 8 x 8 = 7 x 4 = 2 x 4 = 8 6 x 4 = 5 x 4 = 20 3 x 4 =
2 x 4 = 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.

Lesson 2We 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.

Lesson 2 June 18, 2012
Story 1Jack had $3.Jack gave Kyla $2 more.
Jack Kyla
Before $3 $1 $5 $19
After $1 $3 $7 ?
What if Kyla had this amount before?

Who had more money afterwards? How much
more?

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.

Lesson 3Question: 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.

Differentiated instruction for students who have difficulty with
standard algorithms. Use number bonds.

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.

Lessons 4 & 5We 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
