Time Sensitive Math Information

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. Show how you figured it out using pictures (hint: tens and ones model) words or numbers.
3. With the same cards what two-digit number can Dora make that is closest to 66 (note: in order to get credit for this answer a child has to be able to compare the difference between all of the possible numbers to 66 and then explain how they arrived at their conclusion). 
4. Show how you found your answer using pictures, words, or 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.

If you would like feedback about your child's response to these questions, either see your child's teacher very soon or send your child's work to school ASAP.
