Math Mammoth Grade 5-A Worktext - by Maria Miller (Paperback)

About the Book

Math Mammoth Grade 5-A worktext is the student book the first half of grade 5 math. It covers the four basic operations, large numbers & the calculator, problem solving, decimal arithmetic, and graphing & coordinate grid.

Book Synopsis

Math Mammoth Grade 5-A Worktext is the student book for the first half of grade 5. This student worktext contains both the necessary instruction and the problems & exercises (the 'text' & and the 'work'; thus a "worktext"), and is fairly self-teaching. This is the full-color version of the 2023 edition. Please note: The worktext does not include the answer key. The answer keys for grade 5 are sold in a separate book.

The main areas of study in the grade 5-A worktext are:

• the four operations with whole numbers
• place value with large numbers and the judicious use of calculator
• problem solving & simple equations
• decimal arithmetic
• graphing and the coordinate grid

The year starts out with a study of whole numbers and their operations. Students get to review multi-digit multiplication and learn long division with two-digit divisors. We also review divisibility and factors from fourth grade, and study prime factorization.

In the second chapter, the focus is on large numbers and using a calculator. This is the first time a calculator is introduced in Math Mammoth complete curriculum-thus far, all calculations have been done mentally, or with paper and pencil. I want students to learn to be critical in their use of the calculator and use it with good judgment. Every exercise where calculator use is to be allowed is marked with a little calculator symbol.

The third chapter is about equations and problem solving. We study simple equations with the help of a balance and bar models. The main idea is to get students used to the idea of an equation and what it means to solve an equation. Students also do a fair amount of problem solving using the visual bar model.

The fourth chapter is about decimals and some of the operations with decimals (the rest will be studied in chapter 6). Fifth grade is the time when students learn all the basic operations with decimals. In this chapter, we focus on place value with decimals, addition and subtraction of decimals, and multiplication and division of decimals by whole numbers. Multiplying decimals by decimals and dividing decimals by decimals is covered in chapter 6.

In chapter 5, we study graphing in the coordinate grid, line graphs, and average. Today's world has become increasingly complex with lots of data presented in the media, so our children need a good grasp of statistical graphs to be able to make sense of all of that information.

Features

• Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, not just learn "HOW" to do it.
• The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much.
• Very little teacher preparation is required.
• The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material.

The curriculum meets and exceeds the Common Core standards.

Review Quotes

Just want to say thank you! I've been homeschooling for 9 years and I'm going to switch my youngest son (5th grade) to Math Mammoth from Singapore Primary Mathematics 2022. I think he will thrive on the text being addressed to the student rather than my attempts at scripted lessons because math is not my strong suit! I appreciate all the details on your website. I watched some of your teaching videos and my son will enjoy not being "babied" as he feels he is with videos we watched with Singapore. I can tell you are passionate about teaching math and providing excellent curriculum. THANK YOU!! Wish I had found you sooner!!

Hello Maria

My youngest has Dyscalculia, and we have found your curriculum to be fantastic. It allows him to totally grasp concepts and actually get to grips with math. Not a sentence I ever thought I would be able to say. Thank you and have a great week.

I want to thank you for this comprehensive, easy-to-use, inexpensive, EFFECTIVE math curriculum. My children have tried an embarrassing number of other math curricula in the past 2 years, with little gain in understanding. I have finally found a program that is actually teaching my 8-year old to understand the relationship between numbers! But the BEST part is that he said proudly the other day that he is "really good at math!" That sense of accomplishment and ability is SO important to me - I see so many children shut down when they think they aren't good at something. I am SO happy to have found the perfect fit for our family in a quality math curriculum!
