Ice Ice Maybe: An Operations Estimation Game |
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. |
Estimator Quiz | In this activity, students are quizzed on their ability to estimate sums, products, and percentages. The student can adjust the difficulty of the problems and how close they have to be to the actual answer. This activity allows students to practice estimating addition, multiplication, or percentages of large numbers. 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. |

Arithmetic Quiz | In this activity, students solve arithmetic problems involving whole numbers, integers, addition, subtraction, multiplication, and division. This activity allows students to track their progress in learning how to perform arithmetic on whole numbers and integers. 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. |
Name | Description |
Subtracting Using the Standard Algorithm | Students are asked to solve two subtraction problems using the standard algorithm. |
Find the Error | Students are asked to find the error in a partially completed subtraction problem using the standard algorithm and to solve the problem correctly. |
Addition Using the Standard Algorithm | Students are asked to solve two addition problems using the standard algorithm. |
Fill In The Missing Number | Students are asked to complete subtraction problems using the standard algorithm. |
Andy's Book | Students add four two-digit numbers within the context of a word problem. |
Adding Two Digit Numbers Using Properties of Operations | Students are asked to add four two digit numbers by considering how another student added "friendly" numbers first. |
Wanda's Method | The student is encouraged to use compensation to efficiently add multi-digit numbers. |
Subtraction Within 1000 | Students are asked to complete four subtraction problems (within 1000) using strategies of their own choosing. |
Adding and Subtracting Using Properties | Students are asked to complete addition and subtraction problems that can be done more easily by using properties. |
Addition Within 1000 | Students are asked to add four different pairs of numbers (within 1000) using strategies of their own choosing. |
Adding Two Digit Numbers Using Place Value | Students are asked to add four two digit numbers using place value. |
Adding Four Two-Digit Numbers | Students add four two-digit numbers without the context of a word problem. |
Name | Description |
Rampin' It Up | Students will use their knowledge of properties of materials and measurement of length to determine how the properties of different surfaces affect the distance traveled by a toy car. |
DOLO - Dinosaurs Only Live Once? | During this activity, students will create an incubator to save the last dinosaur eggs. Students will use their knowledge of energy to develop a strategy and choose which materials would be best for their dinosaur egg incubator. |
"Amazing Race-Elapsed Time" | In this lesson, which focuses specifically on the elapsed time portion of the standard, students work in small groups in a "race" to solve real world problems involving time. |
Let's Think in Small Units | In this lesson students will make and complete tables to express larger unit measurements in terms of a smaller unit within one system of units. They will use the chart to make comparisons and explain their reasoning. |
Dining Dilemma! | The students will compare different nutritional content of chicken nuggets from many restaurants. They will factor in the calories, the total fat, saturated fat, and sodium levels in the nuggets to rank the nuggets from healthiest to least healthy. Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom. |
Kites for Education MEA | Kites for Education is a Modeling Eliciting Activity which presents students with an engineering challenge in which they must analyze data sets and develop a procedure for ranking different kite models. The product ranked as best by the students will hypothetically be sold to customers and the profit used to purchase school textbooks and supplies for school age children impacted by Haiti's devastating earthquake. |
Jumping Beans: Adding with Open Number Lines | Students will use the open number line as a strategy to add within 1,000. The lesson begins with a formative assessment that evaluates students' strategies for efficiently solving addition sentences within 1,000. In order for students to have practice reinforcing the skill, students will complete the guided practice with open number lines, as well as playing the game, Jumping Beans. To conclude the lesson, students will evaluate a solution to an open number line problem. |
Subtraction Attraction | In this lesson, students will demonstrate fluency in using a standard algorithm to complete story problems involving subtraction with regrouping using multi-digit whole numbers. |
Decoding Decomposing {Adding two 3-digit Numbers} | Students will add 3-digit numbers by decomposing them by place value. It is a useful lesson to reinforce place value concepts when adding. |

Adding It All Up with a Standard Algorithm | Learn to add multi-digit numbers using a standard algorithm in this interactive tutorial. |
Speedy Sam | Help Speedy Sam add and subtract as quickly as possible by using the properties of addition and subtraction in this interactive tutorial. |
Name | Description |
To regroup or not to regroup | This task presents an incomplete problem and asks students to choose numbers to subtract (subtrahends) so that the resulting problem requires different types of regrouping. This way students have to recognize the pattern and not just follow a memorized algorithm--in other words, they have to think about what happens in the subtraction process when we regroup. This task is appropriate to use after students have learned the standard US algorithm. |
Name | Description |
Subtracting: regrouping twice | In this video tutorial from Khan Academy, learn how to subtract in situations that require regrouping twice using the expanded forms of numbers, as well as the standard algorithm. |
Mental technique for subtraction without regrouping | In this Khan Academy video tutorial, consider an alternate algorithm for subtracting multi-digit numbers mentally. This video is best for students that are already comfortable with using regrouping to subtract using the standard algorithm. |
