What should 3rd graders be doing in math




















This article is part of. Kids start learning math the moment they start exploring the world. Each skill — from identifying shapes to counting to finding patterns — builds on what they already know. There are certain math milestones most kids hit at roughly the same age.

But keep in mind that kids develop math skills at different rates. Start predicting cause and effect like what will happen if they drop a toy in a tub full of water. Know the difference between two- and three-dimensional shapes and name the basic ones cubes, cones, cylinders. Understand that numbers can be represented in many ways fractions, decimals, bases, and variables. You will notice that many math concepts and math skills repeat over the Kindergarten, 1st Grade, Second Grade and 3rd Grade levels.

This is due to the fact that math concepts build on each other grade by grade. Students will be expected to have a very good understanding of their Addition and Subtraction Facts at this stage. Addition and Subtraction Math Facts should be mastered by the start of the 3rd Grade. More than one Math method may be taught to solve these problems, including Mental Math.

They will also be placing objects into equal groups, displaying numbers in arrays, and creating number stories. This will extend into the memorization of the easier Multiplication Facts first, then to the more difficult Multiplication Facts.

They will also relate Multiplication to Division. Students in Third Grade will be expected to know how to skip count by 2s, 5s, and 10s ex: 2,4, 6, 8, or 5, 10, 15, They may begin skip counting by other numbers such as 3,4,6,7,8 and 9 as preparation for Multiplication.

They will also continue working on the Math concept of making change. Students who have an understanding of Subtraction will have an easier time with making change.

Students in Grade 3 will learn that each digit in larger numbers has a value, depending on its position in the number. Third Graders will have many opportunities to measure in a variety of ways.

Third graders now mainly solve two-step word problems that require using any of the four operations — addition, subtraction, multiplication, division — to solve. For example: If 3 children pick 4 apples each, and then the group eats a total of 6, how many apples are left?

For example: Round 62 to the nearest ten. Round to the nearest hundred. Your child will also add and subtract within 1, and learn the pattern for multiplying numbers by adding a zero. Your third grader gets precise about the time, solving addition and subtraction word problems about time and telling time to the nearest minute. How much longer did she sleep?

Third graders learn to draw picture graphs and bar graphs to compare numbers in word problems that ask how many more or how many fewer objects there are in one category than in another. Third graders measure the length of objects to the half and quarter inch and show the different lengths on a plot line. Third graders start using multiplication to find the area of a shape by multiplying length times the width. Kids expand their understanding of shapes based on shared properties.

For example, not all four-sided shapes, called quadrilaterals, are squares and rectangles: some are kite shaped and some, like trapezoids, have four sides with different lengths. Your child will be asked to solve real-world problems to find the perimeter of these different shapes, too, by adding the lengths of all four sides.
