First graders study money. In this addition lesson, 1st graders count and add two-digit numbers using dimes and pennies.

In this addition worksheet, 2nd graders add two digit numbers together with and without regrouping. Students complete 40 problems.

In this addition learning exercise, students complete a set of 18 problems, adding one 2-digit number to another. A reference web site is given for additional activities.

Learners complete a total of 12 problems; all problems add 2 five-digit numbers. Must open page from source to view graphics.

Learning how numbers are put together as parts and wholes is a big step in building the foundational number sense of young mathematicians. Here, children are given a number less than 10 and are asked to find as many pairs of numbers as...

Print this activity and have your helper pass it out. The class can use it to practice subtracting single and double-digit numbers up to 20. Some borrowing is required.

Learners are introduced to the concept of imaginary unit and complex numbers. They are taught how to add and subtract complex numbers. Students define a complex number. They comprehend at least two applications of complex numbers....

Show scholars that if they can add two multi-digit numbers, they can add four! They complete 20 practice problems adding three and four-digit numbers. All the equations have four addends and include units. All numbers are whole numbers....

Addition and subtraction are studied in this math lesson. Upper graders add and subtract whole numbers up to 1,000 with and without regrouping.

Add them up! Scholars add up double-digit addends to find sums for 32 equations. There are three examples learners can reference if needed, and they have to regroup for many of these. The equations aren't numbered, so consider doing this...

Those are some long numbers! Scholars write number-form digits in word form and vice versa. The first eight are six-digit numbers and the next eight are seven-digit numbers. There are two examples to get them started. Remind scholars to...

Mixed numbers can be added conceptually, algorithmically, and physically. Have the class visualize mixed numbers by adding fraction bars together. They then discover the algorithmic process that simplifies adding mixed numbers. Finally,...

Once scholars have a grasp on adding fractions, it's time to throw some mixed numbers into the equation! Each of these 14 addition problems has one mixed number and one proper fraction. Skills here include finding a common denominator,...

Encourage young scholars to tap into their inner math-whiz as they add three and four-addend equations. The first 36 problems each have three addends (none over two-digit), and are written horizontally. Next, they complete eight more...

Here is an engaging presentation that challenges your mathematicians to use the techniques of partitioning and halving in order to double or half numbers. After each technique is explained, learners are given a series of numbers to try...

Get a charge out of a great resource! Scholars use an interactive to explore addition and subtraction of integers. They add or remove electrons in an atom model to consider its charge.

Try out a resource using triangles to estimate radicals. An interactive app allows learners to approximate some irrational numbers involving square roots. They find the two consecutive numbers that an irrational number lies between...

Estimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

Eight questions challenge scholars to use mental math while multiplying whole numbers by powers of 10. A tool with bouncing decimals demonstrates how and where the decimal moves. Question types include several multiple-choice, a...

Five questions—multiple-choice, true or false, and a discussion—make up an interactive that focuses on decimals as mixed numbers. Moveable blocks assist scholars in finding solutions. 

Boost mathematicians' proficiency of binary numbers 17 to 24 with an interactive comprised of six questions—multiple-choice, true or false, and a discussion. A color-coded table reveals binary equivalents to aid in the problem-solving...

Mathematicians answer five word problems in an interactive practice all about repaying money using division. A calendar and moveable dollar bills aides participants in finding solutions to multiple-choice, fill-in-the-blank, and...

Brilliant! This presentation helps kids discover all the different way they can make 10. Each slide contains 10 balls, as the kids count, each ball blinks, and the number appears under them to show how many. A plus sign pops up and the...
