Math Mammoth Grade 4 complete curriculum
Math Mammoth Grade 4 complete curriculum belongs to the Math Mammoth Lightblue Series. This fourth grade math curriculum comprises two worktexts (A and B), an answer key, tests,and an easy access to script-made free calculation worksheets, which provide extra practice when needed.
The two books for 4th grade focus on
- multi-step word problems and order of operations
- multi-digit multiplication
- long division and its applications
- problem solving using multiplication and division
- conversions between measuring units
- developing conceptual understanding of fractions and decimals
- geometry topics such as measuring angles, drawing polygons & circles, perimeter, and area of rectangles
Please see the table of contents for 4-A for a complete lesson list.
Some main features of the Lightblue Series books are:
- focuses on understanding of mathematical concepts
- uses clear explanations and lots of visual aids
- mastery oriented: concentrates fairly long on a topic, with fairly few topics per grade
- emphasizes mental math and developing number sense
- very little teacher preparation needed
AN ADDED BONUS! Buying this in Kagi store (as a download), you will also get Soft-Pak programs completely FREE. The 7 programs in Soft-Pak (4 math, 1 language arts, 2 testing) offer both on-screen and printable activities in a low-graphic, high content format. Read more and see screenshots.
Introduction
In 4th grade math, students focus on multidigit multiplication and division, learning to use bigger
numbers, solving multi-step word problems that involve several operations, and get started in studying
fractions and decimals. This is of course accompanied by studies in geometry and measuring.
The year starts out with review of addition and subtraction, graphs, and money. We illustrate word
problems with bar diagrams and study finding missing addends, which teaches algebraic thinking.
Children also learn addition and subtraction terminology, order of operations, and statistical graphs.
Next come large numbers -- up to millions, and the place value concept. At first the student reviews
thousands and some mental math with them. Next are presented numbers till one million, calculations
with them, place value concept and comparing. In the end of the chapter we find more about millions and
an introduction to multiples of 10, 100, and 1000.
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 work on multiplying in parts. We also study 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, lenght, 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. The geometry chapter introduces students to measuring angles, and we do lots of drawing of
different shapes and circles. Area and perimeter are other important topics in geometry.
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 the conceptual understanding, building
a good foundation towards 5th grade math, where fractions and decimals will be on 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 naturally be studied only after
mastering division.
This product also includes an HTML page that you can use to make extra practice worksheets for
computation, and a list of helpful Internet links for each chapter.
