This is a winter themed variation of Silly Creatures Number Logic Puzzles, a fun little booklet that your students can put together in about 3 minutes and features 2 kinds of objects to decipher. This version involves three different objects to interpret, which will really give them something fun to do and most likely fry their brains by 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.

Note: this is the same as the "winter theme three part number logic puzzles," but with "silly icons" instead of "winter icons." This is a sequel to Silly Creatures Number Logic Puzzles, a fun little booklet that your students can put together in about 3 minutes and features 2 kinds of objects to decipher. This version involves three different objects to interpret, which will really give them something fun to do and most likely fry their brains by working logically - and because this is somethin

This is a collection of 8 different Thanksgiving Themed "matrix addition" puzzles which use funky symbols as clues to figure out the answers. They were designed for 2nd graders, but you could use them with advanced first graders, or just throw them at some third and fourth graders to see how they react. They're sort of algebraic puzzles that you can have a lot of fun with and who doesn't like fun? Comes in color and b/w for your printing pleasure! What makes this really cool is that I also in

"On a bad day, I have no ideas. On a good day, I have a lot of wrong ideas. At least with wrong ideas, I can mix them together and come up with a right answer." That's the idea behind this number puzzle, which I've intentionally designed to be really tricky and frustrating (at least, it was for the 3rd through 6th graders I tried it on.) The relationship between the three columns appear to be arbitrary, but there actually is some method to the madness: the students should be encouraged to come

This is a collection of 10 different algebra puzzles that use 3 different variables which are represented as rectangles, triangles and hexagons. Yes, we know that "adult" algebra uses X, Y and Z, but since this is designed to be appealing for our younger students (and because abstraction is still tough for them) I've used these geometric shapes instead. I've also limited the kinds of numbers students use by focusing on using 0 - 9 digit cards. This is so your students will not get frustrated wh

This is a collection of 12 different division reasoning problems that require your students to understanding through written explanations. No, it doesn't mean your students are going to explain the long division algorithm by writing about the steps they took to solve the problem. First of all, who cares? Second of all, it doesn't really show a mastery of the concept of division; it only shows they have memorized the steps in an algorithm that is totally unnecessary to memorize in an age of calcu

What's a tokidoki, you ask? Well, there are several varieties, and basically they are born with a certain number of segments on their body, and then grow new ones over the year. Some are born with 3 segments and add 4 more each year, some are born with 2 segments and add 5 more each year. There are lots of different types of tokidokies and they all grown using different patterns. This activity uses tokidokis to promote the idea of using patterns to solve a problem. If you have a tokidoki that w

“Parity” is the mathematical concept of “evenness” and “oddness.” For example, we know that all whole numbers are either odd or even, and that if you add or subtract evens and odds, certain forms of parity will emerge. For example, if you add two odd or even numbers, you will end up with an even number; if you add an even and an odd, you’ll end up with an odd number. To make things more interesting, if you add an odd number of even numbers (say, 2 + 4 + 6), you’ll end up with an even number. How

You have a locked briefcase that you want to send to your friend on the other side of the country. You put a lock on it and keep the key around your neck. There is no second key, you can't duplicate this key, and you don't want to send it to your friend, because you're afraid it might get lost or stolen. How does your friend open the case? That's a question that has a lot of relevance to the use of prime numbers! But I digress: this is a set of activities designed to enhance your students' un

My school uses Connected Math for it’s 6th grade math curriculum; it’s pretty bad in many ways, but on the other hand, it is much better than all the other 6th grade math curricula I’ve seen, which are complete and unadulterated junk (I’m looking directly at you, Go Math!!) The 6th grade unit on rates and ratios has some pretty good activities in it, but I think the use of gummy worms is pretty lame, because, well, I am a believer in the separation between crappy food and educational matter

Nadia Geddit wanted to get into her building, but she forgot the code to the lock. However, she did remember some clues about the code. These are 5 clues about the code: 1) The sum of the fifth digit and the third digit is 14. 2) The fourth digit is one more than the second digit. 3) The first digit is one less than twice the second digit. 4) The sum of the second and third digit is 10. 5) The sum of all five digits is 30. What 5 digits must Nadia press to make the lock open? How wo

This is the most carefully and completely documented use of the "The Handshake Problem" (also known as the "Glass Clink Problem") that you can find. It spans 5 days worth of lessons, homework assignments, enrichment and an assessment. The beauty of the "handshake problem" is that it can be looked at as a way to represent a problem visually through the use of points and connecting edges, but it can be investigated as a sequence of triangular numbers. This is then be compared to other types of seq

Here’s the idea: your students are learning about coordinate geometry, so you teach them hoe to find the x and y axis, they plot a few points, maybe you play some lame games, and then they’re off and graphing some equations. Bo-ring! These activities teach students about the conventions of coordinate graphing (they are not “rules”, they are “conventions”) and then applies them to the practice of solving actual problems, from delivering pizza to making maps to guide first responders. The activiti

"STOP THAT ZOMBIE! is a truly "hands on" approach to working with addition and subtraction, with links to algebra, patterns and problem solving. The basic puzzle is simple: using the numbers 1- 6, distribute them around a triangle so that each side adds up to 9 (thus, trapping the zombie in his cage!) Where it gets really cool is this: you can arrange those same 6 numbers to add up to 10, 11, and 12 on each side. But the fun doesn't end there: you can differentiate this by using the numbers 2 -

This is a collection of 10 candy corn puzzles that you can print in color, cut out and put onto plates. The student takes the indicated number of pieces of candy corn and distributes them on each character so that the the sum of two adjacent characters comes out to the arrow connecting them. For example, if there is an arrow pointing between mummy and witch, and it says "4," then you can either place 4 on the mummy and 0 on the witch, 1 on the mummy and 3 on the witch, 2 on the mummy and 2 on t

You've got the links, here are 75 different pattern puzzles for you to print out in full color, complete with answers. Set them up as math centers by putting the solutions on the back of the problem, use them as "problem of the day" or send them home with a bag of links for parents to solve with their kids. This set has 3 different types of pattern problems: • Problems where the student "continues" the pattern shown on the card; that is, the pattern shows the first 5 - 8 links that establishes
