Decimal and Whole-Number Operations

Learners build fluency with the standard algorithms: long division of multi-digit whole numbers (including decimal quotients), and adding, subtracting, multiplying and dividing multi-digit decimals. Each algorithm is connected to place value, every answer is checked with an estimate, and the course ends with shopping, fabric and fencing problems.

  • 4 lessons
  • About 85 minutes
  • Fluent operations check: 10 questions
  • Ways to answer: choose an answer, type a number, place on a number line, put in order, sort into groups and write a short answer

What learners will discover

  • Divide multi-digit whole numbers with the standard long-division algorithm, continuing into decimal places when needed.
  • Add and subtract multi-digit decimals fluently by aligning place values.
  • Multiply and divide multi-digit decimals with the standard algorithms and explain where the decimal point goes.
  • Estimate to check decimal computations and solve multi-step problems with prices and measurements.
