This sample chapter from Hurst's book Picturing Math is an excellent resource for using picture books and activities for learning computation.

Third graders can solve multiplication and division problems quickly by recognizing the relationship between the two operations.

The big idea of this lesson is that three (or more) numbers can be grouped together and added. The order of this grouping doesn't matter.

Making ten is one of the foundational strategies for developing flexible numerical thinking, accuracy, and efficiency.

At the end of the year, a lot is going on in our classroom. We continue our center routine for additional practice and to allow for end of the year testing to be completed.

Numbers don't stop at 20! We spend the last week or so of school looking at the numbers beyond 20. Today we do it by looking at the number line.

Second graders solve change unknown story problems using a number line. This lesson gives students a new strategy to attach change unknown word problems.

Second graders can find patterns in 4-digit numbers that will help them when counting over decades and centuries.

Second graders will become more comfortable making sense of equations presented in missing answer (traditional) and missing number ( nontraditional) formats.

Common Core standards encourage the use of models to build understanding in math. This instructional activity shows sometimes reluctant 2nd graders that models are helpful tools in solving mathematical problems.

The connection between subjects is an important one to establish for students. Communicating across subjects is part of the Common Core expectations.

Second graders love to talk about pets and in this lesson plan they can share how many pets they have.

As the result of a Unit assessment, it was found that students showed some confusion with writing time and with adding sets of coins. These skills need to be reviewed to aid in mastery of the Common Core standards for time and money.

This resource allows students to practice fraction computations. Students are able to select parameters that include the type of operation, numerator and denominator max and min, common denominator, and improper fraction. There are ten...

Lesson includes a video & examples showing the common shortcut for multiplying & dividing decimals by powers of ten. [7:59] Provides exercises and word problems for practice.

Use this tutorial to learn what imaginary and complex numbers are, how to write them, and how to perform operations with them. Offers step-by-step examples, video explanations of the examples, and practice questions with answers.

This tutorial shows students how to multiply and divide complex numbers and includes the topic of conjugates. Includes link to a graphing calculator tutorial.

Playing a game for the order of operations engages students in math fact review and builds fluency.

Students will be able to independently practice graphing, teen numbers, and addition.

In this interactive site students get to practice with various math skills in a real life scenario. Those skills include basic subtraction facts using materials, matching number sentences to pictorial representations, and writing number...

[Free Registration/Login Required] In this formative assessment task, learners are asked to explain how rational and irrational numbers differ and why the product of a non-zero rational number and an irrational number is irrational....

SWBAT share their knowledge through the assessment provided

Understanding place value is critical to the Common Core Standards for second grade. Without a concrete understanding, 2nd graders may not fully grasp the meaning of the digits.

Sixth graders are presented with a completed multiplication equation and are asked to use it to find the answers to seven other equations. To do this, they must use their reasoning and estimation skills. Aligns with 6.NS.B.3.
