This task acts as a bridge between understanding place value and using strategies based on place value for addition and subtraction.

This short video and interactive assessment activity is designed to teach second graders an overview of addition (sums to 100) - word problems.

This short video and interactive assessment activity is designed to teach first graders an overview of subtraction (numbers to 100).

This video lecture serves as a review of subtraction up to the number twenty for first graders.

This task provides a context where it is appropriate for students to subtract fractions with a common denominator; it could be used for either assessment or instructional purposes.

Pet Bingo features the following K-4 math skills:
ADDITION & SUBTRACTION:
– Add and subtract up to 10, 20, 100, 1000 and more
– Add up to four digit numbers
– Add and subtract multi-digit whole numbers
MULTIPLICATION & DIVISION:
– Practice times tables 1 to 12

– Understand concepts of area and relation to multiplication and addition

The purpose of this task is for students to select 2 numbers from a set of 3 that sum to 9. The task can be completed for sums equaling any number. Teachers may choose to ask students to write the simple equations they select.

Same But Different is a powerful routine for use in math classrooms. The activity of same but different is an activity where two things are compared, calling attention to both how they are the same and how they are different.

This apparent paradox is the beauty of the activity. It is important to notice the word BUT. Instead of making a choice – am I going to prove that these are the same or am I going to prove that they are different – students are considering how two items can be both. This is a critically important distinction.

Not same OR different, rather same BUT different.

There are categories for addition/subtraction, early numeracy, multiplication/division, measurement, place value, fractions, ratios, geometry, algebra, and high school math.

Same or Different? is a routine that provides students opportunities to construct arguments when comparing objects, such as numbers or shapes.

A routine like Same or Different? provides accessible opportunities for even youngest students to learn how to talk about various features of mathematical objects – quantity, shape, color, orientation, and arrangement, to name a few.

In this challenging instructional task students relate addition and subtraction problems to money and to situations and goals related to saving money.

This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.

The main areas of focus in the second grade math curriculum are: understanding the base-ten system within 1,000, including place value and skip-counting in fives, tens, and hundreds; developing fluency with addition and subtraction, including solving word problems; regrouping in addition and subtraction; describing and analyzing shapes; using and understanding standard units of measure; working with money and time; and introducing multiplication.

The worksheets and printables for second grade math available on this page will enhance any classroom's math curriculum. These engaging second grade math worksheets cover the basics of counting and ordering as well as addition and subtraction, and include exciting introductions to geometry and algebra for future self-assurance in math.

The purpose of this task is for students to select 2 numbers from a set that sum to 5 (or any other number).

Students gain experience and practice with three types of word problems using the "Take From" context: result unknown, change unknown, and start unknown.

This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. However, students should not be discouraged from using individual counting to start if they are stuck. Often students will get tired of counting and devise the shortcut method themselves.
