NRICH's School Maths Topics is a dynamic math resource primarily for grades 3 and 4, although many activities are also appropriate for grades 2 and 5. Topics include number patterns, basic operations, measurement, 2-D and 3-D shapes, and data analysis. You can supplement what you're already doing with these activities, or use them to give kids an extra challenge. As a supplement, choose an activity for kids to complete in small groups -- have them discuss their solutions as a class. Relate the activity to what kids are learning in your more formal lessons. If working directly on the computer, make sure kids don't access the solutions until after the class discussion. If you're giving kids an extra challenge, assign them from time to time as homework -- follow up by asking kids to share their results with the class. Many activities include printable worksheets; however, in some cases, additional materials are needed so be sure to plan accordingly.Continue reading Show less
Key Standards Supported
Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.
Measurement And Data
Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
Number And Operations In Base Ten
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
Operations And Algebraic Thinking
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.
