Units Seven & Eight: The Third Marking Period
Unit One allows students to review and build on prior knowledge. It establishes routines and practices that will be used throughout the year. Unit One has four main areas of focus:
~To explore patterns on number grids
~To review telling time, measuring lengths and using calculators
~To review data concepts and make predictions based on data
~To give equivalent names for numbers
Unit Two focuses on addition and subtraction with emphasis on basic facts and their extensions. Students will work with multi-digit addition and subtraction and using addition and subtraction to solve number stories. The main areas of focus will be:
~To review fact families and number families
~To review and solve "What's My Rule?" problems
~To use diagrams to help solve number stories
~To review algorithms for adding and subtracting.
