MAFS.3.NBT.1.2

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.

Clarifications

Students 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. (Although 3.OA.3.7 and 3.NBT.1.2 are both fluency standards, these two standards do not represent equal investments of time in grade 3. Note that students in grade 2 were already adding and subtracting within 1000, just not fluently.
That makes 3.NBT.1.2 a relatively small and incremental expectation. By contrast, multiplication and division are new in grade 3, and meeting the multiplication and division fluency standard 3.OA.3.7 with understanding is a major portion of students’ work in grade 3.)

General Information
Subject Area: Mathematics
Grade: 3
Domain-Subdomain: Number and Operations in Base Ten
Cluster: Level 1: Recall
Cluster: Use place value understanding and properties of operations to perform multi-digit arithmetic. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Educational Games

Ice Ice Maybe: An Operations Estimation Game:


This fun and interactive game helps practice estimation skills, using various operations of choice, including addition, subtraction, multiplication, division, using decimals, fractions, and percents.

Various levels of difficulty make this game appropriate for multiple age and ability levels.

Addition/Subtraction: The addition and subtraction of whole numbers, the addition and subtraction of decimals.

Multiplication/Division: The multiplication and addition of whole numbers.

Percentages: Identify the percentage of a whole number.

Fractions: Multiply and divide a whole number by a fraction, as well as apply properties of operations.

Type: Educational Game

Estimator Four:

In this activity, students play a game of connect four, but to place a piece on the board they have to correctly estimate an addition, multiplication, or percentage problem. Students can adjust the difficulty of the problems as well as how close the estimate has to be to the actual result. This activity allows students to practice estimating addition, multiplication, and percentages of large numbers (100s). This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

Party Planning: Using Multiplication:

As the end of the year approaches, and your students have already learned several multiplication strategies, this party planning activity can help put all of that hard work into action. Students will be asked to use a menu and catalog to purchase food, decorations and goody bag items for an upcoming party. (I use this right before our end of the year 3rd Grade Luau Party, and have students purchase items that correlate with that theme. However, it can be used to plan an ideal birthday party, 4th of July Celebration, family reunion, etc.) After working together as a whole group, children will work with a partner and, ultimately independently, to solve one and two-digit multiplication and addition problems. Your students will get a chance to be creative and apply multiplication strategies to real world scenarios.
