  1. 1-66th grade math Adding Whole Numbers and Decimals

  2. Objective • To add whole numbers and decimals. • Why? To master one of the aspects of Number Sense in 6th grade math (and beyond) of whole numbers and decimals.

  3. California State Standards NS 2.0 : Calculate and solve problems involving addition … AF 1.1 : Write and solve one-step linear equations in one variable. MR 1.1: Analyze problems by identifying relationships … and observing patterns.

  4. How to Add Whole Numbers and Decimals 1) Be sure that the decimals are lined up correctly. 2) Add each place value carefully. Take your time. Start with the ones or smallest decimal place value. 3) Be sure to carry carefully, when needed. 5) If a decimal problem, be sure to place the decimal in the correct place. 12,600 + 2,835 12,600 + 2,835 12,600 + 2,835 5 12,600 + 2,835 1 35 12,600 + 2,835 1 435 12,600 + 2,835 5,435 12,600 + 2,835 15,435

  8. Objective Review • You can now add whole numbers and decimals. • Why? You have now mastered one of the aspects of Number Sense in 6th grade math (and beyond) of whole numbers and decimals. You can add whole numbers and decimals using mental math, paper and pencil, or calculators.

  9. Independent Practice • Complete problems 8-13 with pencil and paper. • Complete problems 14-19 with a calculator. • Copy original problem first. • Show all work! • If time, complete Mixed Review: 22-31 • If still more time, work on Accelerated Math.
