 * Grade: 3 Unit: 1 Week: 2 Content: Math Dates: 8/27-8/31 **


 * Theme Essential Question: ** Why do we need to be able to fluently add and subtract and tell time accurately?


 * Essential Questions: **
 * How do we solve addition and subtraction problems fluently using estimation to judge the reasonableness of an answer? **


 * Standards **
 * ** 3.NBT.1 ** Use place value understanding to round whole numbers to the nearest 10 or 100.
 * ** 3.NBT.2 ** //Fluently// add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.


 * Objectives **
 * The learner will review place value.
 * The learner will round two and three digit whole numbers to the nearest 10 or/and 100.
 * The learner will fluently add and subtract within 100 using a variety of strategies and will judge the reasonableness of the answer using estimation.

**Product** 1.) They should first estimate their purchases and then find the exact amount of their purchases. 2.) Students should then estimate the difference in cost between two of the items, then find the exact difference between the two items.
 * Assessment **
 * Students will use the weekly sale adds to purchase items up to $10.

**Key Questions** (match Standard)
 * Can the learner use place value to round to the nearest 10 or 100?
 * Can the learner use estimation strategies to judge reasonable sums and differences?
 * Can the learner fluently solve addition and subtraction problems within 1000?

**Observable Student Behaviors** (Performance)
 * The learner will use place value to round to the nearest 10 or 100 given a two or three digit number.
 * The learner will use estimation strategies to judge reasonable sums or differences.
 * The learner will fluently add and subtract within 1000.

**Mathematical Practices** 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning.

Live a frog's life as you hop along a number line in search of flies. Learn how addition and subtraction can be represented as movement along a number line. Fred the frog may even help you get better at adding and subtracting two-digit numbers in your head by decomposing them into tens and ones. Teacher Guide & Student Exploration Sheet Available. Play an addition card game! The goal is to create a sum that is as close as possible to the target sum. Students will deepen their understanding of place value as they get better at playing the game. Many game options allow students to vary the game for more practice. The game can be played with one or two players. Teacher Guide & Student Exploration Sheet Available.

Addition and Subtraction Solve addition and subtraction problems, including word problems involving two-and-three digit numbers with regrouping. Complete an addition and subtraction sentence with missing addends including inverse relationships between and addition and subtraction. Properties of Operations Identify properties of operations such as commutative, associative, and distributive and use them to compute whole numbers, including inverse relationships between and addition and subtraction. This activity will review basic concepts of subtraction: when to subtract estimation regrouping subtracting 2 digit numbers subtracting 3 digit numbers subtracting across zero Add and subtract 2-digit numbers with and without trading. The lesson involves regrouping in the ones place value by adding two digit numbers. A caller say a number up to 12, teams double it and swat the number on a board with a fly swatter. Points kept on a scoreboard. Adaptable for number identification, addition, subtraction, multiplication and division. Student must use knowledge of properties to solve for missing numbers (variables). @http://exchange.smarttech.com/details.html?id=08088143-d212-47c6-9450-376ed2c3c914 Students will gain an understanding of three different algorithms to add two digit numbers. The lesson has examples and a quiz at the end. @http://exchange.smarttech.com/details.html?id=ea9502f8-3a7e-4456-9bca-a849a602f7ee Students will explore mental math skills using grouping strategies to solve addition problems. *Students will understand and use the commutative and associative properties of addition. @http://exchange.smarttech.com/details.html?id=f0b00466-f0ea-4c77-8685-14dfe4e0e8aa Check double digit subtraction problems by clicking on the snowman. @http://exchange.smarttech.com/details.html?id=bb3204a0-1406-41e0-b8f0-37de3cc8050d Exploring addition properties that are always true. @http://exchange.smarttech.com/details.html?id=b8d88333-40e3-41b5-b558-ee3f7bae8030 Everyday Math - Third Edition Grade Three Unit 2 Lesson 1

The applet explores the use of an abacus model for representing numbers and for performing addition In the following lessons, students participate in activities in which they analyze information represented graphically. Students are asked to discuss, describe, read, and write about the graphs and the information they contain. The emphasis on using components of language is natural for students and helps them clarify the information depicted. This unit was adapted from an article entitled "Ideas: Football," by by J. David Keller, Daniel J. Brahier, and William R. Speer, which appeared in The Arithmetic Teacher, January 1993, pp. 264-77. In this lesson, students generate products using a number line model. Students are encouraged to predict the products and to answer puzzles involving multiplication
