Math Mammoth South African Version Grade 4 A and Grade 4 B worktexts comprise a complete maths. curriculum for the fourth grade mathematics studies aligned to the Common Core Standards The Math. Mammoth South African version has been customized to South Africa in the following manners. z The names used are South African names instead of Jack and Jill there are Ansie and Mampho. z The currency used in word problems is rand and cents. z The material is all metric In other words the US customary measuring units are not used. z Spelling is British English instead of American English. z Paper size is A4, Please note that the curriculum is not following the South African official syllabus for grade 4 maths. Instead it simply is a copy of the US version of Math Mammoth Grade 4 For the most part Math. Mammoth exceeds South African standards Some standards may not be covered. In the fourth grade students focus on multi digit multiplication and division learning to use bigger. numbers solving multi step word problems that involve several operations and they get started in. studying fractions and decimals This is of course accompanied by studies in geometry and measuring. The year starts out with a revision of addition and subtraction patterns and graphs We illustrate word. problems with bar diagrams and study finding missing addends which teaches algebraic thinking. Children also learn addition and subtraction terminology the order of operations and statistical graphs. Next come large numbers up to millions and the place value concept At first the student revises. thousands and some mental maths with them Next are presented numbers up to one million calculations. with them the concept of place value and comparing In the end of the chapter we find out more about. millions and an introduction to multiples of 10 100 and 1 000. The third chapter is all about multiplication After briefly revising the concept and the times tables the. focus is on learning multi digit multiplication multiplication algorithm The children also learn why it. works when they multiply in parts We also study the order of operations again touch on proportional. reasoning and do more money and change related word problems. The last chapter in part A is about time temperature length weight and volume Students will learn to. solve more complex problems using various measuring units and to convert between measuring units. In part B we first study division The focus is on learning long division and using division in word. problems In geometry we first revise area and perimeter and then concentrate on the topic of angles. Students measure and draw angles solve simple angle problems and classify triangles according to their. angles They also study parallel and perpendicular lines. Fractions and decimals are presented last in the school year These two chapters practise only some of the. basic operations with fractions and decimals The focus is still on conceptual understanding and on. building a good foundation towards 5th grade maths where fractions and decimals will be in focus. Sample worksheet from, www mathmammoth com 6, When you use these books as your only or main mathematics curriculum they can be like a.
framework but you do have some liberty in organising the study schedule Chapters 1 2 and 3 should. be studied in this order but you can be flexible with chapters 4 Time and Measuring and 6 Geometry. and schedule them somewhat earlier or later if you so wish Chapter 3 Multiplication needs to be. studied before long division in Chapter 5 Many topics from chapters 7 and 8 Fractions and Decimals. can also be studied earlier in the school year however finding parts with division should naturally be. studied only after mastering division, I wish you success in teaching maths. Maria Miller the author, Sample worksheet from, www mathmammoth com 7. Chapter 1 Addition Subtraction, Patterns and Graphs. Introduction, The first chapter of Math Mammoth Grade 4 covers addition and subtraction topics problem solving. patterns graphs and money, At first we revise the technical aspects of adding and subtracting mental maths techniques and adding.
and subtracting in columns We also study some patterns The lesson on Pascal s triangle is intended to be. fun and fascinating after all Pascal s triangle is full of patterns. In the next lesson we study the connection between addition and subtraction and bar models Bar models. help students write addition and subtraction sentences with unknowns and solve them This is teaching. the students algebraic thinking how to write and solve simple equations. The lesson on the order of operations contains some revision but we also study connecting the topic with. real life situations such as shopping Here the student writes the mathematical expression number. sentence for word problems which again practises algebraic thinking. Going towards applications of maths the chapter then contains straightforward lessons on bar graphs. line graphs rounding estimating and money problems.
