Key Facts & Information

LEARNING OBJECTIVE

  • At the end of the lesson, students will be able to fluently add within 1000 using strategies and algorithms based on place value and properties of operations.

A NOTE FOR THE TEACHER

  • When teaching addition within 1 000, try the following in your lesson:
    • Ensure that the learner understands place value
    • Always start adding from the ones, then tens, and then hundreds.
    • If you are regrouping, always write the carried value in the correct place, ie., above the tens column or above the hundreds column.

THEORY

  • Addition is the process of calculating the total of two or more numbers or amounts.
  • HOW TO ADD WHOLE NUMBERS:
    • Write the numbers, so each place value lines up vertically.
    • Add the digits in each place value. Work from right to left, starting with the one’s place. If a sum in a place value is more than 9, carry to the next place value.
    • Continue adding each place value from right to left, adding each place value and carrying if needed. So we always start adding from the ones.
  • Example: 157 + 5 – composing tens
  • If we write it so that the place values line up, it will look as so:

  • Example: 346 + 9 1 – composing hundreds
