**4.1-Unit 2: Multiplicaton and Division of Whole Numbers**Students will take their Unit 1 Assessment on Monday. They have been working extremely hard on Unit 1 and we are confident that they will shine on the assessment. After our Brain Building Day on Tuesday, we will take the Unit 2 Pre Assessment on Wednesday before jumping right in to Unit 2 on Thursday and Friday. Students will be introduced to the first standard in Unit 2: 4.OA.1. This standard requires students to be able to understand and interpret multiplication as a comparison, express multiplicative comparisons with equations and solve problems using multiplicative comparison. Developing a deep understanding of multiplicative comparison will establish a strong foundation for all of Unit 2. Students will explore this standard and practice solving equations using hands on manipulatives and models in our math workshop.

__4.1 Standards for the Week:__*4.OA.1*- Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

__4.2-Unit 5: Decimal Fractions__This week your child will be introduced to their next standard of Unit 5:

*4.NF.7.*

*This standard requires the student to be able to compare and order decimals by using different tools, such as base-ten blocks, 10x10 grids, number lines, or other visuals. A concept that will continue to be emphasized is that a decimal with a 0 in the ones place is less than a whole and represents a fraction of a whole. Students will also use number lines to determine if a decimal is closer to zero, closer to one-half, or closer to one. Your child will be taking notes on the standards throughout the week in their Math Journals. Please remember that these are wonderful study tools that we encourage the students take home (as long as they remember to bring them back!) The students have been taking very neat, detailed notes that I know will make awesome study tools!*

__4.2 Standards for the Week:__*4.NF.7-*Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g. by using a visual model.

**5.1-Unit 1: Order of Operations**This week students are 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 have their Unit 1 Assessment on Friday, September 21st!**

__5.1 Standards for the Week:__*5.NBT.5*- 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.6 -*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).
