3. Number bonds which is fundamental in number sense
development is emphasized in subsequent levels
even when they are not explicit in the textbooks.
We have seen how number bonds is used in Grade
1 lesson (video). 32 is 10 + 10 + 10 + 2. 32 is also
20 and 12. 32 is also 20 + 10 + 2.
4. We have also seen how it is used in the development
of number facts.
5. Lesson 2 August 6, 2012
In Grade 3, we use it doe large number
multiplication when products are found through
partial products.
6. In the differentiated
approach to doing
long division in the
Grade 5 lesson ,
number bonds
continue to play a
prominent role.
49. Lesson 11
How do we help students develop the method to multiply and divide
fraction by a fraction?

54. Additional Example
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.
• Which sentence is best to start off with?
• Do as we read.
• Use paper strips.
• How does the model look like? Can you picture it? How should the
bar change?
Let’s look at a word problem involving fractions.
