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.
