Encouraging Vocabulary Usage

General notes on encouraging vocabulary usage with young children:

  • The goal is to introduce math vocabulary to young children as they explore math ideas with concrete objects, not to make them memorize vocabulary.
  • Introduce math vocabulary as naturally as you would introduce the names of different foods, animals or toys.
  • The more children hear math words used with activities, the more they will begin to use them correctly. Reinforce math vocabulary with everyday things. Whether setting the table, playing with toys, displaying collections on the science table, or cleaning up after dinner, there will be opportunities to reinforce the math words to your students.
