Adding double-digit numbers can seem difficult for some students. But, this Khan Academy video makes this process clear in a developmentally sound way. Students watch as 'Sal' adds the number 46 to 43. He references each number by its...

Learners read the numbers listed in expanded form, standard form, short word form, and word form. They match the descriptions that represent the same numbers.

Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using the...

Third graders construct numbers to the millions place. In this 30-page place value activity, learners create numbers and evaluate the place value of digits. They explore standard and expanded form of numbers. An incredible resource!

Place value to the millions is the focus of this math lesson plan. Third and fourth graders investigate multiple ways to represent a number. They examine place value while studying factual information about Pablo Picasso. Resources are...

Here is a phenomenal lesson on place value to the thousands place.  Learners construct numbers and identify the value of each digit, investigate building numbers using craft sticks and paper plates, and complete other meaningful place...

Daily routines not only help to manage classrooms, they can also provide students with rich opportunities for learning. This activity supports young learners in developing their number sense by counting up the school days on a class 100...

Understanding the distributive property is a big step in developing fluency with multiplication. The fourth video of this series clearly explains this fundamental property using arrays and diagrams. Numerous examples are presented that...

Looking at large numbers can intimidate many young mathematicians. Use Zoe's place value machine to help learners understand the meaning behind each digit in a whole number. After learning about the ones, tens, and hundreds places,...

A quick lesson on how to write an exponential expression in expanded form. All you have to do is write out the base number the identified number of times as represented by the power.

So you have a given number in expanded form where you have to multiply that same number several times. Make it a little easier for yourself and write it in exponential form. As long as the number has the same base being multiplied you...

Identify the base, identify the exponent, write out the base the number of times indicated by the exponent. Then multiply the base as written out in expanded form. Finally simplify your answer and you will have just evaluated an exponent.

Learning new ways to look at basic addition problems can help young mathematicians better grasp place value, expanded form, and carrying. Watch the instructor add two and three-digit numbers together by breaking each number into tens and...

So you have a given number in expanded form where you have to multiply that same number several times. Make it a little easier for yourself and write it in exponential form. As long as the number has the same base being multiplied you...

You are given a number that is written out in words and now you have to write it in numerical form, and you have to write it in expanded form. The teacher helps you identify the period values and the place values to write the words in...

A quick lesson on how to write an exponential expression in expanded form. All you have to do is write out the base number the identified number of times as represented by the power. This would be a great support to your lesson on...

You've been given a number written in expanded form. You have to write it in standard form, and in word form. The instructor does a nice job illustrating and explaining just how to do both of these operations.

Identify the base, identify the exponent, write out the base the number of times indicated by the exponent. Then multiply the base as written out in expanded form. Finally simplify your answer and you will have just evaluated an exponent.

Explore place value through re-writing these two-digit numbers in expanded form. For example, 47 becomes 40 + 7. There is one example to model this, and scholars complete 14 more on their own. Be sure they understand this process as...

Practice place value through writing numbers in expanded form; scholars do this with numbers up to five digits. There are two examples to demonstrate the process, and the problems are split into four distinct sections to keep pupils...

Writing numbers in expanded form is a great way to practice place value, and here scholars do this with numbers up to six digits. There are two examples to demonstrate the process, and scholars complete four distinct sections to keep...

Observe numbers in four different forms. Scholars become more familiar with place value as they match the numbers on the left with those on the right. The twist is that the numbers are shape-shifting! Some are in expanded form, others...

Third graders write numbers in expanded form. In this math vocabulary lesson, 3rd graders write numbers in expanded form using words only, words and numbers, and numbers only. Each student is given three dice to roll. They then write the...

Here is a series of morning math activities which will get your class thinking as they start the day. Simply do one or two every day; the variation in types of math will keep them on their toes and reviewing past concepts. Each of the 16...
