Singapore Math First Grade Understanding Singapore Math® curriculum for grades 1-6 is called Primary Mathematics. There are two books that are used together, a textbook and a workbook. The textbook is used as a class activity book during the lesson, and the workbook is used for independent practice. The year is divided up into two parts, so there is a textbook and workbook A and a textbook and workbook B for each year. (Primary Mathematics, Singapore Math.com Inc. 2001)
Laying the foundation for student success
Concrete
Pictorial
Abstract
Concrete is the students first encounter with the mathematical concept. This is done through a hands on approach using manipulatives as a guide for students.
Pictorial is the second encounter with this mathematical concept. This is done by moving to a picture stage in which pictures are used to model problems.
When students are familiar with the ideas taught. They progress to a more advanced or abstract stage in which only numbers, notation and symbols are used.
Key Terms and Concepts needed for Parents and Students Number Bonds - Number bonds are different pairs of numbers which make up the same number. For instance, the number bonds for 8 are 1+7, 2+6, 3+5 and 4+4 Number bond is typically represented using a picture consisting of 3 circles connected by 2 lines.
Model Drawing - Means translating a word problem into diagrams or models. This technique not only provides a powerful method for solving problems, but also serves as a link to algebra.
Base 10– Students learn the process of adding and subtracting using base 10 strategies. This formative concept allows students to understand these simple operations.
Number Bonds 1. Students are taught to identify parts in a whole.
?
2. Students Make up Stories to illustrate number bonds within 10.

? 3. Students begin to write down the appropriate number bond and the number sentence corresponding to the picture.
4. Students begin to write appropriate addition sentences and number bonds with no pictorial drawings. Operation symbols are also added

A) Fill in the numbers. B) Add or count the baskets. C) Complete the Number Bond. D) Write the answer next to the ?.
4 + 5 = ___?__
Circle the answer E) Complete the sentence.
They scored __?___ baskets in all. They Scored

baskets in all.
Adam has 16 crayons. Rachel has 5 crayons. How many more crayons does Adam have than Rachel? 2. Create bar segments for each of the individuals in the problem.
16
Adam”s Crayons
5
Rachel”s Crayons
3. Show the difference
16 - 5 = 11 1. Start by writing the sentence
Adam has 11 more crayons than Rachel. 4. Solve the problem.
Base 10 Strategies
7+5=? 1) Start by moving three of the red dots into the empty spaces to make one full 10. 2) Rather than reading the problem as 7 + 5 the students now see 10 + 2 3) This change makes it easier to find the answer, which is 12.
Base 10 Strategies without graph assistance
7+5=? 3
2
1) Create a number bond with the smaller number (Which happens to be 5). 2) The number seven is only three away from ten. Therefore we will move three out of the five leaving two behind. 3) Combine the three and the seven to make 10. 4) You now have a simpler set which reads…
10 + 2 = 12
