The main areas of study in Math Mammoth Grade 3 are:Students develop an understanding of multiplication and division of whole numbers through problems involving equal-sized groups, arrays, and area models. They learn the relationship between multiplication and division, and solve many word problems involving multiplication and division (chapters 2, 3, and 9). They learn the multiplication tables, and learn how to use their knowledge of multiplication tables to solve basic division facts.
Students develop an understanding of fractions, beginning with unit fractions. They use fractions along with visual fraction models and on a number line. They also compare fractions by using visual fraction models and strategies based on noticing equal numerators or denominators (chapter 10).
Students learn the concepts of area and perimeter. They relate area to multiplication and to addition, recognize perimeter as a linear measure (in contrast with area), and solve problems involving area and perimeter (chapter 7).
Students fluently add and subtract within 1,000, both mentally and in columns (with regrouping). They learn to add and subtract 4-digit numbers, and use addition and subtraction in problem solving (chapters 1 and 6).
Additional topics we study are time (chapter 4), money (chapter 5), measuring (chapter 8), and bar graphs and pictographs (in various chapters).

Nice, sturdy, convenient cutting boards
My daughter and her fiance do a lot of cooking, and really like the quality and sizes of these cutting boards. I got a similar set last year, and I like how they have held up. I also like the holder. Just wash and oil them occasionally and they should last many years.

Not a happy customer
Color: Brown, Size: 14.9"L x 0.6"W
If you are looking for nice size cutting boards, then these are not for you! They are very small and I didnt like the etching on the cutting boards, they will get filled with things you are cutting. What I least didn't liked don't know if its Amazon fault or the vendor? But the item came in the original box the boards were in, the the top part of the box was open. Everything was in the box but the label was on the box. When I returned it to the UPS store they wanted to charge me$10.19 for a box even though it was shipped without a box finally convinced them to put in a large
envelope and they still charge me $2.75. Not happy at all with this vendor or maybe Amazon?
