 MAT-01 Targeted Standards(NBT) Domain: Number and Operations in Base TenCluster: Understand place value. MAT-01.NBT.02 Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:

## Student Learning Targets:

### Knowledge Targets

• I can identify the base ten model that shows the number of tens and ones asked for.
• I can identify the base ten model that shows a number.

### Reasoning Targets

• I can tell how many tens and ones are in a two-digit number.
• I can use base ten/cubes/pictures to show the value of the digits in a two-digit number.
• I can decide which digit is in the ten's place and the one's place.

### Skills (Performance) Targets

• I can write the number the base ten model shows.

## Rubric / Proficiency Scale

 Score Description Sample Activity 4.0 Advanced Criteria Under Development In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content. - 3.5 In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content with partial success. 3.0 Student is able to correctly answer place value concepts identifying a digit's place, how many tens and ones a number is composed of, and the value a digit has within a two-digit number. I can tell how many tens and ones a number is made of. I can decide which digit is in the ten's place and one's place. I can tell/show the value a digit has in a two-digit number. - 2.5 No major errors or emissions regarding 2.0 content and partial knowledge of the 3.0 content. 2.0 Student is able to correctly answer place value concepts using base ten models as a representation for numbers within 100. I can tell how many tens and ones are in a representation for numbers larger than 19. I can choose/show the base ten model that shows how many tens and ones are asked for. I can choose/show the base ten model that represents numbers greater than 19. - 1.5 In addition to 1.0 content, student has partial knowledge of the 2.0 and/or 3.0 content. 1.0 Student is able to demonstrate beginning understanding of place value concepts for numbers 11-19 using models of base ten as a representation.  Work may contain minor errors. I can choose the base ten model that shows the number of tens and ones asked for. I can choose the base ten model that shows the numbers 11-19. I can write the number the base ten model shows for the numbers 11-19. - 0.5 Limited or no understanding of the skill id demonstrated.
