## Division difficulties and moving forward

This past week, we finished Unit 3 and our specific focus on division. Students made a lot of progress over the course of the unit. While many students are now competent and capable of completing long division with one of a few strategies, some students still need more practice. While we need to keep moving forward with new content to keep pace with the curriculum, I hope that families can further practice division at home with students. I will look for ways to continue to review division when we have extra moments and when it connects to the current topic. Additionally, I will endeavor to assess students again later in the year on the division standards to account for later growth and understanding. Thanks in advance for any and all support you can provide your student with multiplication and division practice!

## Unit 4, here we come!

Starting **January 17th**, we will be switching back to English for math instruction as we begin Unit 4: Equations and Word Problems. Math instruction will continue in English for the next 5-7 weeks before we switch again Spanish.

## A note about math homework

As we have more resources for the 2018 curriculum (the English version) than our older Spanish curriculum (it’s being updated next year!), I will again be able to provide more differentiated math homework for students. This means that the homework pages your child brings home each week will have been specifically chosen based on the understanding of concepts I see them use class. If a student is struggling with either the difficulty or the amount of math homework, please don’t hesitate to contact me.

## Math Vocabulary

I know that the “new math” today can seem confusing and different from what you (and I) learned years ago. To help you navigate this new world with your student, here is a list of the important terms we will be using over the course of Unit 4:

**Compare**– describe quantities as greater than, less than, or equal to each other. (*comparar*)**Composite number**– A number greater than 1 that has more than one factor pair. Examples of composite numbers are 10 and 18. The factor pairs of 10 are 10 and 1, 2 and 5. The factor pairs of 18 are 1 and 18, 2 and 9, 3 and 6. (*número compuesto*)**Difference**– The result of subtraction. (*diferencia*)

**Equation**– A statement that two expression are equal. It has an equal sign. (*ecuación)***Evaluate an expression**– Substitute a value for a letter (or symbol) and then simplify the expression. (*evaluar una expresión)***Expression**– One or more numbers, variables, or numbers and varables with one or more operations. (*expresión*)

**Factor pair**– A factor pair for a number is a pair of whole numbers whose product is that number. (*par de factores*)**Multiple**– A number that is the product of a given number and any whole number. (*múltiplo*)

**Pattern**– A sequence that can be described by a rule. (*patrón*)**Pictograph**– A graph that uses pictures or symbols to represent data. (*pictograma*)

**Prime number**– A number greater that 1 that has 1 and itself as the only factor pair. Examples of prime numbers are 2, 7, and 13. The only factor pair of 7 is 1 and 7. (*número primo*)**Simplify an expression**– Combine like terms and perform operations until all terms have been combined. (*simplificar una expresión*)**Sum**– The answer when adding two or more addends. (*suma*)

**Term**– A number, variable, product, or quotient in an expression. Each term is separated by an operation sign (+, -). (*término*)

Thank you again for all of your support of student’s math learning at home and at school. We’ve come a long way already this year, and still have so much more to learn!
