This curriculum is essentially the same as the US version of Math Mammoth Grade 4, only customised for the international audience in these aspects:
In moneyrelated word problems, the symbol it used is "$" (dollar).
In the fourth grade, students focus on multidigit multiplication and division, learning to use bigger numbers, solving multistep 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 review 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 reviewing the concept and the times tables, the focus is on learning multidigit 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 metric measuring units and to convert between some metric 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 practice 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 math, where fractions and decimals will be in focus.
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 organizing 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 be studied only after mastering division.
Please also see the table of contents for 4A and 4B (in the sample files), which will let you see the topics covered in more detail.
Some main features of Math Mammoth complete curriculum (Light Blue series) are:
The downloadable version includes a worksheet maker (Internet access required) that lets you make extra practice worksheets for many of the topics in the curriculum.
The PDFs in the download version are enabled for annotation. This means that if you prefer, the student can fill them in on the computer, using the typewriter and drawing tools in Acrobat Reader version 9 or greater.
Here is a list of manipulatives that are needed or recommended for grade 4. Measuring tapes are only used in the measuring chapter.
