1 Explanations may be supported by drawings or objects.

I can use place value to add and subtract.
I can use Base-10 models to add and subtract.
I can use regrouping in adding and subtracting.
I can use partial sums and partial differences (decomposing numbers).
I can use open number lines to count up or count back.

* 2.NBT.B.9

Resource #1 Interactive Math PowerPoint Task Cards and Test Prep in two sets.

• Interactive, animated PowerPoint designed for computer/doc camera and Smart Boards.

• No Prep format: Plug in computer and go.

• 40 Word Problems in two sets of 20 each to promote fluency, collaboration, and accountable talk.

• NOTE: This animated, interactive PowerPoint presentation usually involves the entire class. Kids also use it individually or in small groups with any device that has PowerPoint app installed. It ignites the enthusiasm, concentration, and interaction among the students. Learning automatically occurs as they “talk out loud about math”.

• This PowerPoint Tasks Cards resource is designed to show the animations in the Slide Show or Presentation View. Please follow the instructions on slide 2.

• Check the feedback on these interactive resources.

IDEA: As you present the problems, students work on their mini whiteboards. Don’t ask them to raise their hands. Have them raise their whiteboards. Teachers are having GREAT RESULTS!

Resource #2 and #3 are designed for individual or small group use with PowerPoint or Google Slides.

• Each set has 20 problems designed in order of difficulty, following state and district standards.

• Each student uses their digital device to go through the questions but writes down the answer on paper. This fulfills the principle that math learning should involve every sensory system for reinforcement and skill mastery.

• At the end of each set is the answer key and I encourage the students to self-check their work and then turn the results into the teacher.

• NOTE: The visuals and illustrations will grab the students’ attention and focus, however, there are no animations active in either set due to the issues between PowerPoint and Google Slides.

Resource 4 & 5 are 2.NBT.9 Math Printables.

• Same two sets of problems but in gray scale, printable files.

• Save your ink. No Prep, just print.

• Answer sheets included. Change your print setting to black and white or grayscale. These are perfect for take home, reinforcement of the standard, remedial attention, and for teachers who prefer printables to digital.

The feedback from TpT teachers and my fellow teachers at school, who use these grade-level interactive sets of task cards, state that kids are engaged and enthused; that the students are focused on the screen, calculating the problems, helping one another with the answers, laughing at the images and animations, and most of all – TALKING OUT LOUD ABOUT MATH.

We call it the “WOW” factor!

These classroom-tested products have generated excellent feedback. A quote: “I couldn’t believe how engaged the kids were in talking about math.” They support research and best practices.

You will see your students become participants as they problem-solve and receive instant reinforcement on correct thinking about math.

The 40 word problems progressively develop “multiply or divide to solve word problems”, and clarify the entire 2.NBT.9
