Hall Classroom

Here are 7 worksheets to teach and/or review double digit addition and subtraction without regroupng. There are 2 addition, 2 subtraction, 3 mixed worksheets to use. Also, touch points can be drawn on the numbers to assist students on these problems.

Here is a quick assessment to see where your students are with arrays. I know when we taught arrays to our second graders, it was a rough skill. This may help to see where you need to reteach.

Here are flashcards that demonstrate the numbers 0-5 on a five-frame, 0-10 on a ten-frame, and 10-20 on a twenty-frame. These can used in a variety of ways. We use them as warm-ups in our classroom, first having students identify the number quickly. Then we have the students create addition and/or subtraction number sentences with them.

Here is a quick quiz that you can give your students to assess fact families.

Here is a worksheet that challenges students to find the fake fact family. Students have to answer each number sentence, then find which fact does not belong in the fact family.

These posters describe how to use a number line when adding and subtracting within 100. Students need help in describing how they know how to add and subtract. These posters help give them the words they need to talk to their peers.

This assessment covers the second grade standards for adding and subtracting within 1000, with possible regrouping.

These number lines can be used for any activity that requires students to use a number line. They can be laminated and written on to be used as a tool in the classroom.

Here is an assessment that I created for our unit "Number Sense" in second grade. It covers addition/subtraction with number lines, arrays, and even & odd numbers.

Here are addition key words for word problems. These are "highlighter words" in my classroom, where they teach students to highlight these as they read, and then they "light the way" to find the correct operation. Can be displayed whole, cut up for a word sort (with the other operation key words), or placed in a pocket chart for students to manipulate. Enjoy! :)

This assessment covers basic addition facts 0-20. It works with five-frames, ten-frames, facts of 5, facts of 10, and double facts.

This activity allows students to roll two dice, twice to create a number sentence. There is an addition activity and a subtraction activity within these pages.
