### Product Description

** Math Mammoth Grade 4 Complete Curriculum** is a complete math program for 4th grade. It consists of two student worktexts (A and B; provided as PDF files), a separate answer key for each, tests, cumulative reviews, and an additional worksheet maker (Internet access required) to make extra practice worksheets when needed. Note: this is a downloadable product.

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 **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 reviews thousands and some mental math 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 1000.

The third chapter is all about multiplication. After briefly reviewing 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 review 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 naturally be studied only after mastering division.

Some main features of Math Mammoth complete curriculum (Light Blue series) are:

- focuses on understanding of mathematical concepts
- uses clear explanations, lots of visual exercises and pattern exercises
- 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

### Reviews

I highly recommend having your student take a placement test from the Math Mammoth website before deciding which level to start. The curriculum is technically common core aligned, but in most topics goes more in-depth than a lot of choices. You can go back a level, or just purchase the topic that seems to need a little extra work. You can also email the author your finished placement test and she will help you figure out what you need to start with. We love this curriculum for many reasons. Everything you need is all right there in the student worktext. It is written to the student, but I find it useful to sit with my child while she does her math to answer any questions she has and encourage her. The curriculum is in-depth and focuses on mastering concepts and really understanding how to apply the math to everyday situations. There are lots of word problems. The Math Mammoth website is an amazing help. There are videos for almost every lesson, and lots of extra free resources for if you find your student struggling in an area. This is a program that teaches well enough for every student, and is strong enough for gifted students. It will prepare them well for any curriculum you want to choose for high school.

We have not started using the curriculum yet, as we haven't started our school year and this is our first experience with Math Mammoth. My daughter will be in 4th grade this year and she is skilled in math, but doesn't really like it. First here are the basics of what you get. There is no teacher guide- I believe this program is supposed to be student-led. With a complete grade curriculum you get student workbooks, part a and b, answer keys, tests and cumulative review practice, and printable manipulatives for fractions. You also get software that allows you to make worksheets. (It looks pretty useful and includes more than just math. It is very basic though. No bells and whistles.) The workbooks contain all the instruction and practice exercises. They have some color, so that helps them be a little more interesting. There are very few pictures and no photos (not that that is bad- just a fact). Mostly the pictures are graphs, although there is the occasional cartoon clip art or map.

I feel like this is a pretty advanced curriculum. I actually don't think we can start using this without some additional instruction first. Right off the bat there is a review that includes things she hasn't done. Perhaps we are "behind," but we haven't done regrouping with subtraction, for example. Order of operations is introduced very early, but we haven't done any mixed operations yet. There are lots of word problems, which I think is really useful. A lot of mental math is expected, which I also feel is good. The instruction is spotty at times though. For example the directions for learning to estimate/round are very thorough and simple, but in other sections there is basically no instruction at all- just problems. If you are not confident in math, this may not be the curriculum for you. If your child doesn't understand something from the book, you are pretty much on your own to figure it out (no teacher's guide/lesson plans/ideas on how to teach). I would not recommend this at all if your student is struggling with math. If you have a fast learner who naturally loves math, you will probably love this curriculum.

I used Math Mammoth with my daughter for levels 1-3 and just purchased level 4. It is rigorous with plenty of mental math and challenging word problems. Emphasis is put on conceptual learning, not just memorizing algorithms. Patterns in math are shown through examples and student work to help conceptual understanding. I love that the instructions for the student and parent/teacher are in the book and I don't have to open multiple books to do a lesson. It's also budget friendly.
