Ten Sly Piranhas: Subtraction with Goldfish Crackers
Class members listen to the William Wise book Ten Sly Piranhas and act out the story with one child playing the piranha. They use goldfish crackers (eating them to show subtraction) to demonstrate and understand equations they see on...

Goldfish Addition and Subtraction
Engage in a hands-on addition and subtraction activity that is a wonderful tie-in with ocean studies. As the teacher, you will make up equations using construction paper and goldfish crackers.

Penguin Man
These penguins are hungry and it's the job of your young mathematicians to feed them. Each of these large penguin templates has a number printed on it corresponding with the number of goldfish crackers students need to place on it. This...

Go Fish! Student Worksheet
A math and science worksheet prompts learners to simulate how scientists determine populations of animals out in the wild. They use goldfish crackers, paper bags, and a styrofoam cup as their tools. An excellent cooperative group activity!
Curated OER
Go Fish
Help learners discover methods to estimate animal population. They will participate in a simulation of catching and tagging fish in order to estimate the fish population. They scoop and count goldfish crackers, record data, and use...

Go Fish!
Students share a bowl of goldfish crackers. In this lesson on sharing, students see how a limited resource goes furthest when it is evenly shared. Students are allowed to take as many crackers as they would like, and then in contrast,...

Estimation Using Goldfish Crackers: Math
Second graders explore estimation and rounding concepts using goldfish crackers and a song! They solve problems by estimating and rounding numbers and pick numbers within reason to represent certain objects.
Curated OER
Goldfish Subtraction
Students manipulate Goldfish crackers to explore subtraction and number sentences.
Curated OER
Go Fish!
Students collect data, interpret data summarize proportional reasoning. Students determine (with various alternate goods) the number of fish in a nearby pond. Students capture the goldfish crackers, deal with pretzels and then write...

Swimmy's Friends
Students solve problems using various strategies. In this problem solving lesson plan, students read the book Swimmy by Leo Lionni. Students make fish swimming patterns, measure how many goldfish crackers it takes to make a handprint and...

How Many More?
Young scholars complete subtraction problems where they use goldfish crackers as their manipulatives in the problem. For this subtraction lesson plan, students use words and pictures to also show their problems.
Curated OER
Estimation Station
Students explore estimation and count by tens with Goldfish crackers.
Curated OER
Go Fish!
Eighth graders use goldfish crackers to simulate a capture-recapture method of data collection. They fill in a chart and determine the averages. They find the estimated population of fish and the actual population of fish based on the...

Beginning Addition
Students examine the concept of addition by adding two one-digit numbers whose sum is less than ten. They count and add goldfish crackers together, chorally repeating each problem.

How Close Can You Get? Estimating
Students work collaboratively to determine how many crackers are in a large container. They then view a video to see how often people use estimation in their jobs, and another video to watch students work on figuring out appropriate...

Estimation Station
Students use this hands-on math center to explore estimation and counting by tens with Goldfish.

Something Fishy (Statistics)
Students are introduced to a problem involving an environmental issue. They are introduced to the capture-recapture method which involves capturing fish, tagging them, returning them and recapturing another sample. Pupils work in...

CATCH, TAG and RELEASE
Pupils apply estimation strategies for problem-solving purposes. They become familiar with one aspect of a marine biologist's work.

Wildlife Sampling
Seventh graders discuss water issues and its affect on salmon population. They recreate a sampling river with fish (cheddar) and scoop them to tag them (which means they exchange them for pretzel fish.) They complete a spreadsheet to...

Measuring Mass
Third graders engage in a lesson plan that is concerned with the estimate and approximation of different masses. They weigh different objects and compare the different measurements and then use a balance to compare them. Students define...
Curated OER
Go Fish:
Third graders imagine that they are asked to determine the number of fish in a nearby pond. To count the fish one by one, they could remove the fish from the pond and stack them to one side, or mark each fish so they would not count them...

Healthy Snacks. Healthy Packaging
Fourth graders research how to select the most cost-effective snacks. In this consumer practices lesson, 4th graders compare packaging labels and come to conclusions on how cost effective the product is. Students discuss their findings.

How Many Lemons Does It Take?
Learners discuss and explore different methods that can be used to estimate from the video. They practice estimation skills by recreating a sample problem from the video. Web sites containing other estimation activities are included
