## Gr. 3: How Many Ways Can You Show Me:

This lesson was developed and used at the beginning of the year to assess students' inital understanding of number sense.

Grade: 3/4
Purpose: Initial assessment of students' understanding of number sense. Student Grouping: Rich Talk: Mini Lesson done with small group/whole class Rich Task: partners or small groups Questions: see below ## Assessment:
Diagnostic: Can students verbally identify and construct 3-digit numbers? Can they use math language (greatest, least, greater than, etc.,) to justify their answers?
Formative: Can they represent their understanding in different ways (using manipulatives, pictures, words etc.)? Summative: Students will submit work with partner for assessment. |
Curriculum Expectations:
- Compose and decompose three-digit numbers into hundreds, tens, and ones in a variety of ways, using concrete materials (e.g., use base ten materials to decompose 327 into 3 hundreds, 2 tens, and 7 ones, or into 2 hundreds, 12 tens, and 7 ones);
## Materials:
- SMARTBoard (with questions on it)
- Paper, pencils - manipulatives (base ten, cubes, dice etc.) - Work sheet with questions (as supplimented for students who need it).
## Student Example:
## Next Steps:
Reflection Lesson: Using the work that students did with partners, have students peer-evaluate their answers. Take off the names of the partners, and have students reflect whether they agree with their answers, and why? Or what do they think a better answer could/would look like? |
