ICSE Class 7 Maths, Unit 2: Ratio and Proportion
From the CISCE curriculum. 8 key concepts, about 4 days of study at 20 to 30 minutes a day.
What this unit aims at
This theme will focus on developing children’s ability to solve higher problems on the use of ratio and proportion in daily life in this class. Children are enabled to use ratio, proportion and their properties appropriately in problem solving. The idea of percentage, unitary method, simple interest, time, work and speed are also introduced through simple daily life problems. Children will appreciate that this is the part of mathematics that they can use the most in their daily lives.
Your child should be able to
- recall ratio and proportion done in early classes
- solve problems using unitary method (getting feel of how formulae for calculation of simple interest and understand percentage as a fraction with denominator 100
- re write fractions and decimals into percentage and vice-versa
- solve problems related to profit and loss (single transaction only)
- apply simple interest (time period in complete years) in daily life situations
- solve problems related to speed, distance and time
Key concepts in this unit
- Ratio and proportion (revision)
- Unitary method continued, consolidation, general expression for unitary method
