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.
Public School in Chile
Lesson 2Can we get the multiplication facts for, say 4, from 2 x 4 and 5 x
4?
Lesson 1 June 18, 2012
2 x 4 = 8
5 x 4 = 20Problem
10 x 4 =
5 x 4 = 20
9 x 4 =
2 x 4 = 8
4 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 5We studied a problem that was used with a group with Grade 3
students in hawai’i

Before $3 $1 $5 $19
After $1 $3 $7 ?
What if Kyla
had this

before?

Story 2
Kyla had $3 more than Jack.

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 6Question: 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?
Lesson 3 show a basic bar model solution in Grade 4.
Lesson 6 June 20, 2012

$4686
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.
Lesson 7We studied the strategies to help struggling readers as well as
those weak in representing problem situations.
