# Even

## Using Ten Frames inside your Classroom

Ten-frames are relatively new to India. They are very useful at the beginning for learning the single-digit numbers. They also facilitate automatization of addition facts with single digit numbers. In addition, they can provide a lot of conceptual clarity wrt odd-even.

Three versions are included:

## Functional Equations - Part 2

In Part 1, I explained the different techniques to solve functional equations. In most cases, the steps to solve them are similar to those in solving algebraic equations. However there is one scenario where using the algebraic method to solve a functional equation may lead to an incomplete solution; i.e., only a subset of functions that solve the FE may be identified and not the complete list. This error is known as pointwise trap.

## The Odd-Even Tale

W e are introduced to the concept of an even number and an odd number in primary school or even earlier. Any natural number divisible by 2 is even; if it is not, it is odd. The definition is extended to integers once we learn the arithmetic of negative whole numbers. Then we make simple observations such as: the sum of two even numbers is even, as is the sum of two odd numbers, and sum of an even number and an odd number is odd.

## Generating the n-th Prime

Here is an unusual way of generating the prime numbers. It is taken from a letter written by Ronald Skurnick of Nassau
Community College (New York, USA) to Mathematics Teacher (National Council of Teachers of Mathematics) and published in the November 2009 issue of the journal.

## Fun time with Numbers

Mathematics is more about concepts and practice than anything else. Why not, then, start early to play certain games with the children and do some maths in the process? We bring you some interesting number games.

## Numbers

This worksheet is designed to help students get an insight into the definition of concepts related to the number system and also to help them understand how numbers are linked to other subjects as well.

## Magic with Mental Maths

Children learn and understand mathematical concepts best when engaged in hands-on activities and games. Language is an important aspect in teaching mathematics and activity time is perfect for reinforcing mathematical talk. Discussions, talking out and language are an important part of a math class, often undermined. Manipulating everyday objects and playing games allows children to figure out and grasp the apparently abstract math concepts.
