Product Description
This set of 24 “Function Machines” task cards are perfect to use as whole class warm-ups, small group instruction, math stations or centers, or even as intervention groups to work on problem solving and algebra thinking. Although designed to be used with fourth and fifth graders, these cards would also be perfect to use with older students needing additional review with algebra thinking. The 24 problems included require students to use different operations (addition, subtraction, multiplication, and division) to solve a variety of input/output problems.

Students may be able to see the mathematical pattern (ex. “This is a
times 3, then subtract 4 pattern.”) or may end up using guess and check strategies
to solve the problems. Students are not expected to use algebraic thinking—but I DID pull some of my top students to show them how to write these “expressions” with variables. They LOVED it!

The goal? To get students thinking deeply about math and recognizing that they can use patterns, guess and check, and other strategies to help them understand! This is basic computation—but using the brain in an entirely different way than a fill-in-the-blank worksheet. Answers are included as are three rubrics to use to help in scoring the Standards for Mathematical Practice! Cards are included in both color and low-ink, black and white versions for ultimate flexibility. There are blank recording sheets that can be used for students to track their work, or they can simply do their work in a notebook.

WHY DID I CREATE THESE?

Over the years I have noticed that students are often in search of an easy answer…a “fill in the blank”. The simple fact is, math is sometimes more complicated than that! In this set of task cards I want students to struggle…something many have never had to do!

In these input/output problems, students need to recognize that when you put a number in (left side of chart), “something” happens in the machine and a new number comes out. It could be something simple—like the machine could add 3 or double the number—or it could be more complex—like the machine multiplies the number times 3 and then takes away 1. These more complex operations are not immediately obvious and require students to do some real algebraic thinking, guessing and checking, and reasoning.

When I first started, I heard lots of “I don’t get it!” and “It’s impossible!”, so I projected a card on the screen and talked through my guess and check strategies. Full color photos are even included with some teaching ideas!

WHAT IS THE CHALLENGE LEVEL?

Cards 1 - 12

These cards involve one step—for example, “add 12” or “double”. They are great to get started…and may be enough for some students! We did the first four as a class, and then students worked in partners to try the others.

Cards 13 – 24

These last 12 cards have TWO steps…making the pattern FAR more challenging to find. Cards may have patterns such as “multiply by 9, then subtract 2” or “multiply by 3 and then add 8”. All four operations are included. These are NOT easy! Students may get frustrated but encourage them to persevere, work together, and use their brains! These would also be perfect for an enrichment group or a station for fast finishers.
