Unit: Adding and Subtracting

BIG IDEAS:

(taken from “Big Ideas by Dr. Small”):
  1. A personal “invented” algorithm is often more meaningful and sometimes equally efficient as a conventional algorithm.
  2. Decimals are an alternative representation to fractions, but one that allows for calculations that are consistent with whole numbers.

STUDENT LEARNING GOALS:

GOAL: I can use strategies to estimate sums and differences of decimal numbers.
GOAL: I can add whole and decimal numbers.
GOAL: I can subtract whole and decimal numbers.

CURRICULUM EXPECTATIONS:

  • add and subtract decimal numbers to hundredths, including money amounts, using concrete materials, estimation, and algorithms (e.g., use 10 x 10 grids to add 2.45 and 3.25);
  • solve problems involving the addition and subtraction of whole numbers, using a variety of mental strategies;
  • use estimation when solving problems involving the addition and subtraction to help judge the reasonableness of a solution;

Hope students and parents find this helpful! Happy mathing!
