**5.1-Unit 1: Place Value, Powers of Ten, Order of Operations, Multiplication, and Division**First, in this unit, students will focus on standards 5.NBT.1 and 5.NBT.2 which focus on understanding the powers of 10, as well as multiplying whole numbers by the powers of 10, and multiplying and dividing decimals by the powers of 10 (and explaining the patterns in the number of zeros in a product or quotient when multiplying or dividing by a power of ten). In addition, students will learn to recognize decimals to the thousandths place and how to round decimals to the nearest thousandth.

Next, students will concentrate on standards

*5.OA.1*and

*5.OA.2*which require students to be able to correctly follow the order of operations when solving expressions (5.OA.1) and interpret both written and numerical expressions (5.OA.2).

Finally, students will be working on standards 5.NBT.5 and 5.NBT.6 which focus on multiplication and division, respectively. Please notice that with division, fluently dividing with the standard algorithm is not a 5th grade expectation (or one of the strategies focused on in the standard), but of course if the kiddos are ready for it (which most of them already are), we will certainly be doing some extension work with it :) We have lots of hands on activities to practice these concepts in math stations, so it's going to be a fun week!

Students will write their "I can" statements in their math journals for each standard, take notes and record examples. Beyond the mini lesson, students will practice these standards during their independent work time and in iReady Math. Plus, students will complete "Quick Checks" to make sure they are mastering the standards as we move along in the unit.

**The Unit 1 Assessment has been tentatively scheduled for**Friday, January 24th. This date could change depending on how quickly we are able to move through the unit.

__5.1- Unit 1: Standards for the Unit:__

*5.NBT.1*__- Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.__

*Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10.*

__-__**5.NBT.2**__- Fluently multiply multi-digit whole numbers using the standard algorithm (or other strategies demonstrating understanding of multiplication) up to a 3 digit by 2 digit factor.__

*5.NBT.5**Fluently divide up to 4- digit dividends and 2-digit divisors by using at least one of the following methods: strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations or concrete models. (e.g., rectangular arrays, area models).*

__-__**5.NBT.6***Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.*

__-__**5.OA.1****(Review)**

*5.OA.2-*

__Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921,__

without having to calculate the indicated sum or product.
