Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends

In 250-500 words, provide a reflection that explains how using questioning strategies builds on prior instructional sessions, encourages student content exploration, and develops problem solving strategies. How are questioning strategies used as a guide to determine appropriateness of instructional resources and curriculum materials in order to adapt instruction? Math Questioning Strategies

Part 1: Questioning Strategies

Grade: 2nd Grade

Math standard (in the area of algebra):

2.OA.3 Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends

· Learning objectives: Students will be able to articulate what even and odd numbers are. Explain even and odd using strategies and representations including physical tools and drawings. Students will be able to identify a group of objects as being even or odd and write an equation to show an even sum has the same addends (e.g., 5 + 5 = 10, 6 + 6 = 12).

Five probing questions that can be used as pre-assessment and formative assessment questions:

1. What is a “pair”?

2. What numbers do not make a pair out of 0-20 (grouped by 2’s)

3. What number do make a pair out of 0-20 (grouped by 2’s)

4. How do you know that numbers are odd?

5. How do you know that numbers are even?
