Measure the length of the notepad and desk in millimeters and centimeters and their mass in kilograms and grams. Notice how the precision and accuracy differ for each measuring device.
Classify the different types of numbers we use, and learn how numbers and operations relate to one another. Start with counting numbers and then add integers, rationals, algebraic, and, finally, real numbers to the line.
Find out how many different combinations of four-legged chairs and three-legged stools you can have after covering each leg with one of 30 tennis balls to silence the chairs whenever they're moved.
Statistical analysis allows us to organize data in different ways to draw out potential patterns in the variation. Review and compare data represented in a bar graph and accompanying tables depicting relative and cumulative frequency.
Control the slope of lines passing through the origin (0, 0). Keep track of what changes when the slope becomes positive or negative, and when slope is larger or smaller than 1.
Do figures with the same area have the same perimeter? Arrange and rearrange 12 square tiles on a grid, and then measure the perimeter of each shape you create.
Use a "linkage strip" to to build quadrilaterals with different sets of lengths. Once you build a quadrilateral, see if you can deform it into a different quadrilateral with the same side lengths.
Use a "linkage strip" to build triangles with different side lengths. When you build a triangle, see if you can deform it into a different triangle while keeping the side lengths the same.
Count the number of raisins in seventeen half-ounce boxes of raisins. Then come up with a solution to determine how many raisins are in Brand X's or Brand Y's box of raisins.
Is there a relationship between the volume of a sphere and the volume of a cylinder of equal diameter and height? What about the volume of the sphere and the cone?
Using three sets of data from a second grade class, think of an aspect of the data you would like to focus on and then choose the type of graph (line plot, stem and leaf plot or histogram) that best represents that aspect.
