## CHAPTER 1 Numbers to 10

Most students coming to grade 1 would be able to count by rote and learn the numbers up to ten and beyond at the kindergarten level. The goals of this chapter are to lead students to more efficient counting strategies with one-to-one correspondence, to read and write numbers in numerals and words, to compare the number of objects in two or more sets as well as to order numbers in ascending and descending orders.

## CHAPTER 3 ADDITION WITHIN 10

In this chapter, the part-whole situation is used to introduce the concept of adding by counting all. Subsequently, students will learn about adding by counting on where more objects are added to a set in before-after situations. The counting-all and counting-on strategies are ways for students to add two numbers.

## CHAPTER 4 SUBTRACTION WITHIN 10

Two early concepts of subtraction are introduced in this chapter- the ‘take away’ and ‘part-part-whole’ concepts. The instructional activities enable students to recognize these two meanings of subtraction. Ways to subtract include methods of crossing out, use of number bonds and counting-back.

## CHAPTER 5 POSITIONS AND ORDINAL NUMBERS

In other chapters, students are taught to count with numbers (cardinal numbers). This chapter shows another use of numbers in the naming of positions (ordinal numbers). Students will learn how to identify cardinal numbers based on their roles and the form they take (i.e. 1 and 1st, 2 and 2nd), as well as the positional language (i.e. first, last, before, after, between and next to) and directional language for left and right.

## CHAPTER 6 NUMBERS TO 20

The informal concept of place value will first be introduced in this chapter through the process of grouping objects up to 20 into 1 ten and ones. This also facilitates counting on from 10. The ability to distinguish between a group of ten objects and loose ones helps students in the comparing and ordering of numbers. This is done so by making a 10 and then comparing the ones.

## CHAPTER 7 ADDITION AND SUBTRACTION WITHIN 20

In previous chapters, students would have mastered addition and subtraction facts within 10. This chapter continues with students learning more ways of addition and subtraction within 20. New strategies such as making 10 and adding the ones are introduced for adding a 2-digit number with a 1-digit number.

## CHAPTER 8 SHAPES

Shapes are all around us. To be able to make sense of the various shapes, students will learn to identify three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders, and spheres) and two-dimensional shapes ( squares, rectangles, triangles, circles, trapezoids, half-circles, and quarter-circles) around them. In this chapter, students will also learn to partition shapes into halves and fourths. Activities and practices are provided to familiarize students with the vocabulary. They will learn to describe the shares using words such as halves, fourths, and quarters, and phrases such as half of, fourth of, and quarter of.
