This is the last of this series of task cards using the theme of a "piggy bank" (remember those) to develop understanding and skills using pennies, nickels, dimes and quarters. (Sorry fans of the half-dollar and silver dollar...) This is a sorting activity: students take a set of cards, look at the amount stated in the piggy bank and the coins outside and if they match, put it in the "correct" part of the sorting mat (included!) - if it's not a match, put it in the "incorrect" section of the so

This is a collection of task cards where students are given two clues about what coins are inside the piggy bank: the first is the value of the coins, but since there could be many different combinations, there is a second clue, which specifies how many coins the student has to use. Fun! There are two sets of cards: one is in easy-peasy to print black & white, the other is in cutesy colors (pink and light blue.) You can print out the cards, cut and laminate them and have them for the rest of

How much Cash is in that Stash? If you've ever struggled with finding a fun and effective way to teach the distributive property of multiplication over addition and subtraction, this is the activity for you. Using the example of a suitcase full of dollar bills, students will learn how to effectively count the cash in groups by dividing up the cash into smaller rectangular arrays, whose products can be combined to find a solution. This activity includes a sample problem, specific teaching instru

Ben and Ilene are having an argument: they are looking at a number line with a 0 on one end, and 1 million on the other end. The question is: where would 1 thousand be? Ben & Ilene have different insights into the problem: Ben says that 1,000 is a large number and so is a million, so it must be close to that side. Ilene says that 1 thousand is much smaller than 1 million, and it belongs closer to 0. Is either of them correct, or is one of them "more correct" than the other? I've included 5 exam

Do you have pattern blocks? Traditionally, we know the triangles as sixths, rhombi as thirds and trapezoids as halves. But what if we changed this a bit? Suppose the trapezoid was not 1/2, but 1/4? What would that make the green triangles? What would "1" look like? If you want to deepen your students' understanding of fractions using manipulatives and having children work together on a very engaging and challenging set of tasks, then you'll want to buy this.
