**STANDARDS FOR MATHEMATICAL CONTE****NT**** FOR THIS UNIT**

Vocabulary is so important for 4th grade math! Here are some flash cards to help you with the math terms we'll learn this year. They are split into 2 groups because the files are so large.

*During the first unit, we'll work on thinking about numbers in multiple ways! This picture is an example of one of the math warm-ups we do every day in class.*

**Use the four operations with whole numbers to solve problems.**

MCC4.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

MCC4.OA.2 Multiply or divide to solve **word problems** involving multiplicative comparison, e.g., by using **drawings** and **equations** with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.

*We'll be learning several different strategies to multiply numbers this year. It's important to know more than one way to solve a problem. For multiplication, these students solved problems using partial product, repeated addition, and the traditional algorithm. *

MCC4.OA.3 Solve **multistep word problems** posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using **equations** with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and **estimation** strategies including **rounding**.

**Gain familiarity with factors and multiples.**

MCC4.OA.4 Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.

**Here are some games to help with this concept!**

**Generate and analyze patterns.**

MCC4.OA.5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself.

**Generalize place value understanding for multi-digit whole numbers.**

MCC4.NBT.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.

**Some resources that can help you understand Place Value:**

**Video that will help with Expanded Form**

Place Value to the 100,000 place

PV- You set the number of digits

MCC4.NBT.2 Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

Practice! Increase the difficulty and try multiplication and division!

MCC4.NBT.3 Use place value understanding to round multi-digit whole numbers to any place.

Use place value understanding and properties of operations to perform multi-digit arithmetic.

MCC4.NBT.4 Fluently add and subtract multi-digit whole numbers using the standard algorithm.

(As you master these skills, work to improve your speed or increase the level of difficulty!)

MCC4.NBT.5 Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

Practice! (You'll need scratch paper.) Please remember to use your strategies!

**Extra help with Multiplication!**

fun practice- Be sure to have paper ready to work these out!

MCC4.NBT.6 Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using 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, rectangular arrays, and/or area models.

Work on speed and accuracy! Once you've mastered this level, you can increase the difficulty!
