Math Antics: Integer Addition and Subtraction

Symbols make everything so much more concise. Young mathematicians learn to write addition and subtraction expressions — including those involving variables — from verbal phrases. Bar models help them understand the concept. 

Develop the rules for adding rational numbers. Pupils continue to work on adding integers. Young mathematicians use their experiences to develop the rules for adding integers with like and unlike signs. They finish the lesson plan by...

Apply addition and subtraction of integers to solve problems with rational numbers. Pupils apply the rules for adding and subtracting integers to add and subtract rational numbers. Class members represent the problem with equations and...

Whether your pupils need extra help or they simply need to practice their basic computation skills, this packet will do the trick. It includes a written rationale, answer key, and over 10 pages of double-digit addition and subtraction...

After reviewing double-digit addition and subtraction up to and from 100, learners are introduced to addition and subtraction up to and from 10,000. A grid is used along side number decomposition to help them solve a word problem...

Understanding the inverse relationship between addition and subtraction is essential for developing fluency in young mathematicians. Zoe and RJ explain how three numbers can form fact families that make two addition and two subtraction...

In this exercise, students practice integer addition and subtraction with substitution. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Students complete a series of learning exercises to practice addition and subtraction.

As a follow up to his video on adding integers with the same sign, Duane created this shortcut video to make life easier. He tells learners they can ditch the number line and just add the absolute value of each number and attach the sign.

Boy I would have loved adding integers if I had known this short cut. Without explaining why it works Duane tells viewers that to determine your answer's sign when adding integers with different signs all they need to do is write down...
