Teaching Integers
Preamble: It is important to state at the outset that manipulatives, which are designed to aid in the understanding of certain concepts, are not meant to be a replacement for the axiomatic development of the subject. Their purpose is essentially to enable students to construct their own mental models for mathematical concepts.

Math talk in the classroom
To answer the above question, let us ask ourselves a few more questions. Does a classroom where the teacher asks questions that can be answered with a simple ‘yes’ or ‘no’ provide scope for students to share their true understanding of knowledge?

Thinking out of the Box – A Worksheet
Monika was teaching ‘Nets of Cuboids’ with Class 5. During the reflection and discussion after the sessions, the mathematics teacher pointed out two misconceptions that arose during her sessions. The cuboid that she chose included two square faces. Some of the students formed the misconception that the net of a cuboid must have at least one pair of square faces. The worksheet given below is intended to address this misconception.

Introduction to Counting
Children’s understanding of numbers begins naturally as they explore the world around them—even in infancy. Through repeated interactions with objects and the language used in their environment, they gradually build early number concepts.
