What Class 7 Mathematics covers

One thing each chapter sets out to make you able to do, in the order the book teaches them.

Build 1,00,000 by stepping from the largest 3-digit number through the largest 5-digit number, adding one at each turnCh 1Large Numbers Around Us
Recognise a written arithmetic phrase as an arithmetic expression, and state that it has exactly one valueCh 2Arithmetic Expressions
Explain why a difference too small to see can still decide whether an object worksCh 3A Peek Beyond the Point
State what a letter-number is and why the chapter calls it thatCh 4Expressions using Letter-Numbers
State how many angles two intersecting lines form, and how many different measures those angles can haveCh 5Parallel and Intersecting Lines
State the rule that turns a height arrangement into a sequence of numbers, and apply it to a drawn line-upCh 6Number Play
Name the three vertices, three sides and three angles of a labelled triangle, and write the triangle's name in any vertex orderCh 7A Tale of Three Intersecting Lines
Explain why a fractional speed does not change how a distance is computedCh 8Working with Fractions
State what has to be true of two figures for them to be congruentCh 1Geometric Twins
Recover two integers from their sum and their difference by systematic trial, and say why the search always closesCh 2Operations with Integers
Say why writing out a number's factors one by one is unreliable, and name the two things that go wrong with itCh 3Finding Common Ground
Convert a decimal into a whole number over a power of ten, and backCh 4Another Peek Beyond the Point
Distinguish a statistical question from one that a single look-up answersCh 5Connecting the Dots...
State what bisection means and what the extra word perpendicular addsCh 6Constructions and Tilings
Read a level hanging bar as an assertion that two collections agree, not as a sum to be carried outCh 7Finding the Unknown
