Optional Math Assignment 1

Dora has 3 cards each with a single digit printed on the face. The cards read 3, 5, and 7.

1. What is the largest two-digit number (the number of greatest value) Dora can make with her cards?
2. With the same cards what two-digit number can Dora make that is closest to 66. Show how you found your answer using pictures, words, and numbers.

Rather than showing your child how to solve this problem, provide a variety of tools (e.g. number line, hundred chart, counters) and observe their strategy. Assist them in articulating their explanation.
