## Units Seven & Eight: The Third Marking Period

**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:**

Unit One

Unit One

~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.
