Playful Mathematical Inquiry - Number Concepts Grades 3 - 5
The ideas below are just ideas. This is NOT meant to be used as a unit. You will need to do some form of a pre-assessment to find out what your students know and then based on this information, combined with the learning standards in the curriculum, you will design learning opportunities to meet the needs of your students and unique context. The ideas below are just meant to inspire.

Number Concepts Inquiry Questions

Place Value Sliders
This activity was inspired by something I saw Kim Sutton do years ago. She calls it "Aerobic Place Value". I use these cards to help build students understand of place value. I begin by using large demonstration ten frames or base 10 blocks and build a number on the board that all students in the class can see. Depending on the number of digits in the number I was building, I would pass out the appropriate corresponding Place Value cards. For example, if I built 235 with ten frames, I would pass out all the hundreds, tens, and ones cards to the students. Then I would ask "Who thinks they have the parts of my number?" The students with the 200, 30 and 5 card would all come to the front. We would check the numbers with the representation on the board to see if they are correct. I would explain this is the expanded version of my number but that when we write numbers, we use standardized notation. Then I would model how the "Place Value Slider" cards slide together to make the standard number.

Place Value Tent Cards
Another way to build place value understanding is to use tent cards when building numbers. I use these when I represent a number with the whole class or in small groups and I have the students use these when they are building numbers independently.
