FACT: Students need more practice solving subtraction problems. FACT: This collection has lots of subtraction problems. FACT: Not all subtraction problems are the same: some are "take away," some are "let's compare one with another," some are "I have something and took away this, now I have this...." This is a collection of over 200 different "BIG Busy Bee Hive" puzzles where students practice subtraction in a context that is fun and thoughtful. That is, yes, they get lots of opportunities to do

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 90 puzzles (30 at each level) of Advanced "Square Knot" Puzzles focused on practicing problems solving for 1st through 3rd graders using addition and subtraction. The format is the same as other square knot puzzles, with larger numbers. Why you should try these: One of the things that we should be emphasizing from the very earliest of ages is mathematics as problem solving. This is more than writing a bunch of word problems: problem solving is about using various techniques for

79 89 99 119? 129? Take 2: 134 124 114 84? 74? Do your students struggle to count by 10s across 100? If they're doing mental math, then they probably will at one time or another. So why not help them practice this so they don't say things like "75, 85, 95, uh, uh, 105?" This is a "three-fer" - you get the group game "roller coaster" where a group of students compete cooperatively to count up and down by tens between a bottom and top number. For example, the first students says 78, the next one

This "product" is an exercise in the form of a "lightly" competitive game that uses addition and subtraction on the number line (which was invented in 1685 by the mathematician John Wallis) that students can play in any number of configurations (pairs, triplets, etc.) and in any number of ways (rolling a single die, rolling 2 dice, using the numbers individually or in combination, etc.) There are versions that use 3, 4, 5 and 6 rolls. There is a number line under each game for your students prac

Are you sick and tired of drilling & killing your kids on the combinations of 10 and just saying, "okay, there's nothing fun about this, so let's just move on." Sorry, I've got to call BS on that. Because learning combinations of 10 is also an opportunity for your students to do some problem solving, do some algebraic thinking, as well as make many, many mistakes. These are NOT worksheets! They are puzzles and are designed to be "hands on" and "manipulative." That is, your students will work w

Okay, you're teaching your kids how to do two and three column addition.... WHAT A SNOOZE! I promise you, this is going to be fun! Here's how it works: you've taught your students about regrouping/carrying in multi-column addition, and they've done a few problems and you want them to have a little more experience with it while doing some deep thinking. This is the activity for you! This collection of "ink blot addition puzzles" will engage your students in a completely different way, because

This is a collection of 9 different colorful Cuisenaire Rod "make the road" puzzles which challenges your students to cover a path using exactly one of each rod. Each one has a different colorful background. This is a great activity that your students can do independently during a work time or placed in a math center. There's a handy chart you can fill in with your students' names to keep track of which puzzles they've completed, with fillable form fields. There is also an option for students

This is one of a series of activities that helps children “break down” numbers. One of the things that I’ve noticed about mathematics curricula is that there is a lot of focus on putting numbers together, but not enough on breaking numbers apart. Perhaps it’s because breaking numbers apart is a lot harder to teach and learn; after all, addition is commutative, and it’s sort of fun, because you get more (except when you’re using negative numbers.) But in order for children to learn how to do thin

This is a set of 48 different coin puzzles: 24 of them show a piggy bank, and the student adds up the total and records it. The other 24 show a piggy bank with a coin missing, and the total amount in the piggy bank; the student has to figure out the missing coin. Those are "missing addend" problems in that the student knows the partially filled amount and the total and has to find the missing piece. This is formatted both as individual "task cards" and worksheets - I'd prefer you use them as ta

This is the same as Number Logic Puzzles Silly Creatures with a Valentines theme, which should really motivate your students! This is a fun little booklet that your students can put together in about 3 minutes and we’ll really give them some fun working logically - and because this is something you purchased from me, your kids will also have a chance to make their own puzzles to share with one another. Ain’t that cool? Comes in b//w and color booklets - the color booklets have been formatted t

One of the chief critiques I have heard about math instruction is that our students know all about how to do a procedure; they just don’t know when it applies. This is an activity that tries to correct this by having students cut out 15 different number strings of 3, 4 and 5 numbers (all single digits), and then “classify” them into one of three groups: “make 10,” “doubles” and “doubles + 1” (also known as near doubles.”) They then paste them into the chart and solve them using the strategy th

This is a set of activities that focus on helping first and second graders memorize the doubles from 1 - 10, with special focus on the "hard doubles" of 7, 8 and 9. There are two different games, and 20 different puzzles involving "number searches" where students find a number and its double nearby. Students also practice writing doubling and halving equations. There is also a set of "locate and calculate" assessments where students locate a doubling equation and then record it.

This is a collection of 95, yes, you heard it correctly, 95 different "equation search" puzzles that target different kinds of computational strategies. There are actually 15 or so different puzzle types, with 6 different iterations (that is, same puzzle with different numbers.) So if your students need additional practice, you can have them do more of them. Actually, I've automated all these puzzles to generate random numbers, but that' another matter. For example, there is a search sheet where

This is a game I invented which can be played by two to three players. Each player gets dealt 4 cards which they place face up in front of them. By selecting cards from the "select pile" (face down) or the "discard pile" (face up), players try to make a "run" of 4 consecutive numbers in a skip counting pattern. The set includes skip counting cards for 3, 4, 5, 6, 7, 8, 9, 11 and 12s. You can easily modify this game to make it trickier by having students try to get 5 or 6 cards in a row. My stude

The concept is simple: add two adjacent hexagons to find the sum and fill in the hexagon ABOVE them, and subtract two adjacent hexagons to fill in the difference in the hexagon BELOW them! Sounds easy, right? Well, maybe not: it's not like you can just start in the middle row and move up and down: to solve it, you have to locate the right place to start, which may be a row up or down, or near the top or bottom. As you fill in each of the solutions, more and more clues emerge, and eventually th
