#### MAT-05.NBT.05

 MAT-05 Targeted Standards(NBT) Domain: Number and Operations in Base TenCluster: Perform operations with multi­digit whole numbers and with decimals to hundredths. MAT-05.NBT.05 Fluently multiply multi-digit whole numbers using the standard algorithm.

## Student Learning Targets:

### Reasoning Targets

• I can choose strategies flexibly to solve multiplication problems according to the numbers in the problem (such as the distributive property or breaking numbers in to place value parts).

### Skills (Performance) Targets

• I can efficiently and accurately multiply whole numbers (up to 3-digit by 2-digit) using the standard algorithm. (Efficiently meaning reasonable amount of steps and Accurately meaning correct answer)
• I can use my understanding of the base ten system to solve multiplication problems involving large numbers.

## Rubric / Proficiency Scale

 Score Description Sample Activity 4.0 There are no advanced criteria as this standard is foundational in the application and use of the standard algorithm to multiply multi-digit whole numbers. - 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 fluently multiply multi-digit numbers using the standard algorithm. I can efficiently and accurately multiply whole numbers (up to 3-digit by 2-digit) using the standard algorithm. (Efficiently meaning reasonable amount of steps and Accurately meaning correct answer) - 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 multiply two, two-digit numbers using strategies based on place value and the properties of operations. I can choose strategies flexibly to solve multiplication problems according to the numbers in the problem (such as the distributive property or breaking numbers in to place value parts).  I can use my understanding of the base ten system to solve multiplication problems involving large numbers. - 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 multiply a whole number (up to 4 digits) by a one digit number using strategies based on place value and the properties of operations; and illustrate and explain the calculation by using equations, arrays, or area models. I can choose strategies flexibly to solve multiplication problems according to the numbers in the problem (such as the distributive property or breaking numbers in to place value parts). - 0.5 Limited or no understanding of the skill is demonstrated.
