LearnZillion's 3rd Grade Math lessons do an excellent job of covering some key standards, so kids' progression from second to third grade is a smooth one. For example, in Grade 2, kids learn about place values up through thousands, how to add and subtract within 100, and how to use models to add and subtract within 1,000. In the Grade 3 module, kids build on these skills before moving on -- they'll also begin to multiply and divide by interpreting whole number products and quotients of whole numbers.
Lessons are organized by grade-level standards, so you can easily find a lesson that's relevant to your instruction. Once you've found one, view the coach's comments first to prepare: They review the standards covered in the lesson, important prerequisite skills, and common mistakes. The commentaries also provide some helpful teaching tips. Next, have kids view the video lesson in small groups as an introduction to a skill, and then come together as a class to discuss the concepts. Finally, have kids complete the guided practice alone or in pairs. Be sure to have students pause the video to write their answers on a sheet of paper, and then resume the video to see the solutions.Continue reading Show less
Key Standards Supported
Measurement And Data
Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
Number And Operations In Base Ten
Use place value understanding to round whole numbers to the nearest 10 or 100.
Number And Operations—Fractions
Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Explain why the fractions are equivalent, e.g., by using a visual fraction model.
Operations And Algebraic Thinking
Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.
Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.
