Two-Step Problems and Arithmetic Patterns

Learners plan and solve two-step word problems with any of the four operations, write equations with a letter for the unknown, and check that answers are reasonable by estimating. They then hunt for patterns in the addition and multiplication tables and explain why patterns such as 'four times any number is even' must always be true.

  • 4 lessons
  • About 85 minutes
  • Two-step problems and patterns check: 8 questions
  • Ways to answer: fill in the blanks, choose an answer, match pairs, type a number, put in order and sort into groups
