Math Mammoth Grade 4-A and Grade 4-B worktexts comprise a complete math curriculum for the fourth grade mathematics studies.
In the fourth grade, students focus on multidigit multiplication and... More > 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, the order of operations, and statistical graphs.
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.< Less
Math Mammoth Grade 4-B complete curriculum focuses on multi-step word problems and order of operations, multi-digit multiplication, long division and its applications, problem solving using... More > multiplication and division, conversions between measuring units, developing conceptual understanding of fractions and decimals, and geometry topics such as measuring angles, drawing polygons & circles, perimeter, and area of rectangles.

In Place Value 4 the focus is on place value with thousands, ten thousands, and hundred thousands - till one million, and a little bit even beyond.
The first lessons review and deal with thousands... More > or numbers with a maximum of four digits. These are for deepening the student's understanding of place value. It is crucial that the student understands place value with these numbers before moving on to larger numbers. These larger numbers can be very easy as long as the student understands the basics of how our place value system works.
The lesson More Thousands, then introduces numbers beyond 10,000. After learning these larger numbers, we also study addition and subtraction, comparing, and the idea of multiples. In addition to column-form addition and subtraction, the book also contains a lot of mental
math problems. In studying mental addition and subtraction, the similarities to adding smaller numbers are stressed, which helps the students to understand how to add/subtract these bigger numbers.< Less
The Math Mammoth Grade 2-A and Grade 2-B worktexts comprise a complete math curriculum for the second grade mathematics studies.
The main topics during second grade, as in first grade, are the study... More > of addition and subtraction and place value up to 1000.
In the second grade, children learn to add and subtract two and three-digit numbers mentally and in columns (under each other). They learn to carry to tens and to hundreds (also called regrouping), and how to borrow either from the tens or from the hundreds. The topics of borrowing two times and borrowing over zero tens are in this curriculum left for the third grade.
Other topics studied are reading the clock to the five-minute intervals; measuring length, weight, and volume; shapes and a few simple geometry concepts; and money topics. This curriculum aims to concentrate on a few major topics at a time and study them in depth.< Less
