This lesson focuses on forming numbers to meet specific requirements. Students carefully read information and understand mathematical language in order to find appropriate solutions. Using the problem-solving strategies of looking for patterns and establishing an organized list will aid students in finding all the possible solution sets. Illuminations provides instructions and an activity sheet necessary for completing the lesson.

Students will:

  • Experiment with numbers to find all possible ways to combine a two-digit square number with a three-digits square to form a five-digit address number.

NCTM Standards and Expectations:

  • Use the associative and commutative properties of addition and multiplication and the distributive property of multiplication over addition to simplify computations with integers, fractions, and decimals.
