Thinking out of the Box – A Worksheet
Monika was teaching ‘Nets of Cuboids’ with Class 5. During the reflection and discussion after the sessions, the mathematics teacher pointed out two misconceptions that arose during her sessions. The cuboid that she chose included two square faces. Some of the students formed the misconception that the net of a cuboid must have at least one pair of square faces. The worksheet given below is intended to address this misconception.
Worksheet (Based on the Tricky Truth about Visualising Fractions)
Here is a worksheet that teachers can use to check their students’ understanding of fractions, in the context of the accompanying article. It may be used for students in classes 4, 5, 6 and 7 as appropriate, to assess their understanding.
Worksheet based on Ten-Frames (Class 1)
Make similar pictures for any of these: 5 + 6, 5 + 7, 5 + 8, 5 + 9 and find the sum
Worksheet based on Geoboard (Class 6)
Make a square. Now release any one corner to get a triangle. Which type of triangle did you get? Consider both types of triangles, i.e., those classified by either side or angle.
Fun with Dot Sheets
The ‘WorkShhet’ series is back, with perimeter and area. Pages 1 and 2 are a worksheet for students, while pages 3 and 4 give guidelines for the facilitator. This time we explore shapes with given perimeter or given area using the dots or the grid.
Cross-Number Puzzle
This cross-number puzzle is a follow up to the article on Fact Families in the same issue. An addition fact family is essentially a set of three natural numbers, such that the sum of two of these numbers is the third.
Fact-Family Worksheet (Addition-Subtraction)
Fact-Families are a group of 3 numbers {a, b, c} such that a + b = c
