Operations with integers - I

Worksheet overview

Descripción:

In this unit, we revise the basic ideas of integers and we use them to practise the following operations: sums and subtractions. Before starting this unit, students should have studied integers in class in the traditional way. These activities can be used as a complement to reinforce and understand the concepts and the operations better. The numbers that appear in each window are generated at random. This allows you to use the window indefinitely and practise a lot of different exercises. Numbers usually consist of only one digit so the calculations can easily be done mentally. Magic squares with sums and multiplications are used in the exercises, however the main objective of this unit is to learn things about integers.
