This is a rounding game I developed for a colleague at my school: I am a working teacher (as I have been for the past 37 years) so I know stuff. And here’s what I know: games are fun, learners like to play games, and games should exercise the learner’s mind in a variety of ways. Which is how I developed the “rounding” and “un-rounding” games. The “Rounding Game” is your basic bingo game: you turn over two cards, round off the number to the nearest ten, find that rounded number on the bingo board

This is a set of puzzles where students work independently to estimate how many cubes it will take to cover a digit or a written number, then cover it with rods of different lengths, and re-organize them on a grid to show how many orange and white rods it is equivalent to. The student then reads the number as tens and ones and writes it down. This is a fun activity for kindergarten and first graders, because it helps students to develop estimation skills, and then carry them over to other number

This is a set of lesson plans with an awesome set of 10 different "Mystery Number" activities. Seriously, do you want a FECKING GOOD way to transform what appears to be a really boring lesson ("Here's how you round off two digit numbers, kiddies!') into a lesson that includes reasoning, hypothesis testing, problem solving AND collaboration! Ten different booklets: a "Sample" to demonstrate to your students, plus 9 more for them to work on individually or collaboratively. AND there's a FECKING

These are highly unusual puzzles that are a great way to practice place value while stimulating your students' abilities in deductive reasoning. Each puzzle is set up as an "acrostic" that has to be filled in vertically and horizontally. The "beginner" puzzles are simple to solve, but they are valuable in that they help students to stop thinking of assembling place value by "order" (such as ".8 + .04 = .84," instead of alternating ".04 + .8 = .84") There are 20 different puzzles that use ones a

It's wild, it's crazy, it's Jack Gabarino! Great for enhancing your students' problem solving skills.... Machina! Machina! Machina!

Greetings friend & fellow educator, Here we go again: just when you thought you had everything fixed up and all your ducks lined up in a neat little row, I’m back to give you some straight talk about place value, because, as I’m fond of saying, you’re teaching it wrong. Not only are you teaching it wrong, but you probably don’t even understand much of it yourself. Oh, you thought you knew everything, just because you bought a few games and did some random stuff with those silly “foldables” th

This packet includes a cover letter for parents that describes the importance of doing math over the summer break, and features a handy chart with a list of the 6 games that are part of this pack, along with a checklist for the dates when they are played. If the child follows the chart, he/she will have practiced math over 50 times during the summer. There are 6 games in the packet, which can be played as partners. They practice addition, subtraction, place value and estimation, and includes ga

I designed this for the first grade teachers at the schools where I work: they wanted something some kind of "morning warmup" for their kids which would be based on a "daily number." So, I took the name of "Our Daily Bread" bakery that used to be in my neighborhood (their slogan was "prepare to meet your baker"), and made it "our daily number" and then put in the different ways you could write the number. I made two different versions which you can mix and match. One is aligned to the "Go Math!

By the Digits is a fully interactive activity to teach your students about place value, regrouping, addition and estimation. Simply tap the "round" number and a random number will appear in the "digit" column. Write that digit in the ones or tens place. Continue for 7 rounds, add up the ones and tens and see how close to 100 you got. This comes in a "demo" version, which is a single board, and a "competition version" where two teams can compete against one another (mad shoutout to Karol who sug

Tired of the old "make a flat" game? Do you want your kids to enjoy learning about and using place value? Close to a Flat challenges children to think about place value when planning strategy to win a game: in 5 rounds a student chooses between cubes and rods to get as close to making a flat as possible, or in 6 rounds, choosing cubes, rods and flats to make a thousand cube. This game includes puzzles for kids to take home, as well as mats to keep track of cubes, rods and flats. There is also a

Number Snakes is a game that develops strategies dealing with place value, numeration, seriation and proportionality. Students choose two cards to make a double digit number, name it, and then decide on which "band" of a snake it should go. However, as more bands of the snakes are filled in, the game becomes more difficult, as careful attention must be paid to how far apart each number should be. There are 7 different levels of the game, from filling in 3 spaces, to filling in 8 spaces, as wel
