o A 6-meter strip of paper folded into twelfths, to be used as “walk on”integer number lineo Graph papero Post-it Notes of two different colours• Read the plan for the upcoming three sessionsWeeklong Overview:Session 1 will introduce a new type of number: integers. Several models for integerswill be shown: a number line that extends "to the left" beyond zero and two-colouredcounters. (Although two-coloured counters can be purchased, it is easy and lessexpensive to use large white beans, which students can colour using felt tip markersor crayons.)Session 2 will address addition and subtraction with integers using the number linemodel and the two-coloured counter model.Session 3 will be devoted to multiplication and division of integers using the model ofarithmetic patterns.Because this is the last session of the Number and Operations unit, there needs to betime allotted for students to reflect on the mathematical process standards that wereused during this unit:• Modelling and multiple representations• Mathematical communication• Problem solving• Connections: both to real life situations and to other areas of mathematics(algebra, geometry, and information handling)
