Use this guided set of equations to help scholars add double-digit numbers with decimals. They examine two examples before trying these on their own, many of which require regrouping. All of these have decimals to the hundredths place....

Each of these addition equations involves two addends that are multiples of 10. Although there isn't any regrouping necessary, some of the sums are three-digit. The first 16 of these 28 equations are vertically oriented and the second 12...

Practice adding decimals by completing 26 practice problems. Scholars examine two examples before trying these on their own. They add two and three-digit numbers with decimals, regrouping when needed. Not all numbers have decimals, but...

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...

Show young mathematicians that they are fully capable of mentally adding two-digit numbers. They start by solving 12 two-addend problems (all with two-digit numbers and aligned horizontally). There is no room to show work. Consider...

To commute or not to commute, that is the question. The 26th segment in a 32-segment lesson focuses on the effect of performing one transformation after another one. The pupils develop the procedure in order to multiply two 2 X 2...

In this horizontal addition worksheet, students add 1 through 3 digit numbers together horizontally. Students complete 16 addition problems.

Learners write out and solve 12 horizontal four-digit addition problems.

In this column addition activity, students add four-digit numbers together with decimals that represent money. They then turn the horizontal problems into vertical problems and complete 20 of them.

Here's some basic practice adding single and double-digit numbers in three different formats. First, learners complete two horizontal addition equations. Then, they find the sum for two vertical addition problems. Finally, scholars...

In this place value addition practice instructional activity, students solve 16 problems that require them to add 4 addends. The addends have 1, 2, 3, and 4 digit numbers.

In this addition worksheet, students solve 40, two digit addition problems displayed in a horizontal format.  Regrouping is required for some of the problems.

In this math instructional activity students will add two and three digit numbers. Students will synthesize answers for 80 horizontal math problems with regrouping.

In this addition practice worksheet, students solve 40 problems that require them to add 3 addends. The addends have 1 and 2-digit numbers.

In this addition activity, students add two and three-digit numbers together and convert them from horizontal to vertical problems. Students complete 12 addition problems with regrouping.

Give your mathematicians some practice with three-digit numbers as they complete these addition and subtraction problems. There are six vertically-formatted equations to start, then learners add to and subtract from eight numbers...

These addition and subtraction problems probably aren't written the way your scholars are used to seeing them, especially since they have double-digit addends and subtrahends. This set of eight horizontal equations gives...

In this addition worksheet, 1st graders complete single digit addition. Students solve for 6 horizontal problems, tracing the numbers, and coloring the correct number of shapes to demonstrate the addition problem that is given.

In this addition activity, students solve horizontal addition problems. They count on to find the missing addend.

In this horizontal addition worksheet, students enhance their addition skills by solving the horizontal, single digit addition problems. Students solve 60 problems.

In this addition worksheet, students solve a total of 20 horizontal problems. Worksheet is part of a subscription site with links and is labeled as a sample.

In this horizontal addition activity, students add the 4 numbers to equal a four digit number. Students add to solve 16 problems.
