I used to think that if a kid could count to 1000, then they had a good understanding of three digit place value. After many years of teaching math to kids of all ages, I have found that I could not have been more wrong. I know think about place value understanding all day long. I find that it is the single biggest thing that holds kids back from developing conceptual understanding of bigger math ideas like multiplication, division, fractions and decimals. I have made it my mission to make sure the kids I work with in grades 2 and 3 have an excellent understanding of three digit place value so they are ready for bigger ideas by upper elementary. When I get an upper elementary student in need of intervention the first thing I do is check for a deep understanding of place value.
This August as I was prepping for back to school, I got Fishing Around with Place Value Riddles written by Linda over at Primary Inspiration. This is a product that works extra hard and I have put it to good use with some of my students in grades 2-5.
My second graders are responsible for numbers up to 1000. This means I want them to be able to count forward and backward in this range, skip count, order numbers, build numbers and be able to add or subtract 10 or 100 from any of these numbers. The biggest thing is that I expect all of this to be done with fluency. This time of year we are only a few months into second grade but I always have kids who are meeting these end of second grade standards by this time of year. This is when I like to introduce a challenge to these kids. These place value riddles are an excellent match. These kids get to stretch their understanding of place value and keep their brains engaged in learning more math. They have to think outside the box and gives them something to work towards. For these learners, I made a set of cards and placed them in a small plastic container. I then gave each of the kids who were ready for this challenge a Poly Envelope and a record sheet. Then they are free to come and grab riddle cards as they need them and work together or independently to figure out the riddles. Once a week or so during Guided Math I pull this group and we go over answers and work together on any riddles they are stuck on. As the year progresses and more kids meet my second grade standards, they will be invited to try these out!

Grade 3Third graders should have a good understanding of three digit place value and be ready to take it to the next level. I have found these cards are an excellent match for my third graders. I have used them several times this year for whole group instruction, partner game time and Guided Math centers.
|The game board made an excellent Guided Math center. Kids pull riddle cards and answer them to progress through the game board. They love when they land on a fish and get a free turn!|
Grades 4 and up
I have used these cards in fourth and fifth grade with the entire class as a choice math center. This is when the cards are all in a tub along with the options described above and a few others from the packet. Kids can write their own, play with the game board, solve and order and more. This lets them review important skills and pull things together. I have also used the riddle cards during transitions and line-up time. When I pull older students to my own space for intervention, I use these riddles in many of the ways I described for third graders.
