Number balance
description: View item in the U of T Libraries catalogue The Number Balance activity kit is perfect for teaching kindergarten and primary mathematics. This kit makes math easy, interactive, and hands-on for students. It helps them visualize number relationships and operations such as addition, subtraction, and comparisons by allowing students to manipulate and place weights on the t-scale. By participating and manipulating the weights students can see whether what they have done has balanced or tipped the scale. An example activity would involve having students hang weights from any two numbers on the left side of the balance and then having them place a weight on the other side of the scale where they think the sum of the other two weights is. The kit contains one large (oversize) t-scale and 20 weights for students to manipulate and place. It can be used as a demonstration tool, as a tool for free exploration, or even for group work. By making mathematics concepts, like addition, subtraction, and comparisons, visual and hands-on for students, the Number Balance activity kit is a great tool for teachers to use in order to engage younger students with math.

Big Time classroom clock kit
description: View item in the U of T Libraries catalogue There are fun times to be had with the Big Time Classroom Clock Kit! This featured activity kit allows students to practice telling time in a hands-on and interactive manner. The kit consists of 1 large clock for teacher demonstrations and 24 mini-clocks for use by students. Additionally, a booklet offers guidance and tips for designing activities and lesson plans featuring the clocks. The kit is especially pertinent to the Ontario Mathematics Curriculum for Grades 1, 2, and 3, which requires that students become familiar with reading both analogue and digital clocks. The kit remains relevant as students progress from first identifying hours to later dealing with increments in minutes. The OISE Library’s Curriculum Resource Collection carries a number of books which might supplement lessons on measurement and telling time. Zip Around: Time is a game which aims to make telling time engaging and interactive. The game features cards which lead students through a fast-paced question and answer game in which they gain experience reading analogue and digital clocks. Books such as Time to Learn About Measuring, Time to Learn About Seconds, Minutes & Hours, and Measuring: Seconds, Minutes, and Hours discuss measurement and telling time with a primary grade audience in mind.
