Towards a just, equitable, humane and sustainable society

Introduction of pre-requisites for addition

Chapter 2: Fun with Number

This chapter deals with concepts such as grouping, counting, and estimation of objects. It is designed in such a way that the students will be able to recollect methods, such as addition and subtraction, which they studied in the second grade. This chapter also focuses on concepts pertaining to place and place value, and it introduces three-digit numbers to the students. Moreover, in this chapter, multiplication is addressed in the form of skip counting.

Activity 1: Counting the collected objects (MA5116)

Students are asked to collect the tamarind seeds scattered on the floor. Subsequently, they are instructed to count the seeds they collect, followed by a discussion about counting and comparison.

This activity’s objective is to make them understand the cardinality of numbers and compare numbers as greater, smaller, or equal.

Activity 2: Ring toss (MA5116)

Small objects (e.g. tamarind seeds) are scattered on the floor. Students are asked to throw rings over them. They must estimate the count of the objects inside the ring and answer immediately without counting. Thus, this activity enhances their ability to estimate the quantity of such objects.

This activity aims to help students estimate amounts without counting.

Activity 3: Grouping into bundles (MA5117 A&B)

Beads or tamarind seeds are used to teach the place value of two- to three-digit numbers. Concepts of grouping and skip counting are also addressed to help students understand the relationship between ones, tens, and hundreds.

This activity’s objective is to help students identify the place and place value of a given digit in a number, and understand the relationship between ones, tens, and hundreds.

A worksheet will also be provided (Worksheet 1).

Activity 4: Understanding place value using concrete materials (MA5118)

Students are asked to represent the given number using the concrete cards given to them.

The objective of this activity is to reinforce the idea of place value with the help of concrete materials.

Activity 5: Arrow cards (MA5118, MA5123)

Arrow cards are given to the students to reinforce the idea of place and place value. The teacher can ask them to write down the number from the given arrow card or split the number using the same.

Activity 6: Grocery shop inside the classroom (MA5125)

Students are given fake currencies. The teacher can set up a mock grocery shop using the materials available in the school compound. One student can be the shopkeeper, while the others can be the customers who purchase items from the shop in exchange of cash.

The objective is to make the students understand how to split a number according to the place value, by connecting it with a daily life activity.

Worksheet 2: Represent a number in four ways (MA5119)

Activity 7: Skip counting (MA5120)

A number line (e.g. 101–200) is drawn on the floor, and students are asked to jump based on the 2s or 3s, and so on.

The objective is to introduce the basics of multiplication through skip counting, in addition to helping the students identify the number pattern and the subsequent numbers.
