In this lesson, students explore arithmetic patterns to help solve a real-world problem involving addition operations. This lesson supports the 3rd grade standard of identifying arithmetic patterns and explaining them using properties of operations.

This resource could be used an a precurser for a lesson on comparing areas of circles and squares. There is guess and check involved, as well as digging deeper to find the correct answer. Students could do part of this on their own device, using GeoGebra to help with graphing the equations. If students do not have access to devices, then the teacher can use it as a class discussion.

This includes questions that can be posed to students, as well as visuals to make the entire task make sense to students. Answer is included.

You Pour, I Choose presents students with a real-world application of which cylindrical container holds more soda. Students will find the volume of soda in two different sized cylinders.

This is a 3 act lesson by Dan Meyer.  In this lesson students ask and answer, "How long does it take the sink to fill up?", after viewing a video of a leaky fauct.

This Three-Act task shows students a video of how Dan messed up his Nana's chocolate milk proportions. Using a double number line, students try to find ways to fix the mistake using different ratios.

This is a three act lesson in which students investigate the volume of 2 different cylinders made from the same size of paper. Students determine which would container would hold the greater volume of popcorn, or if the volume would be the same.

In this Dan Meyer Three Act, students are asked to determine how many levels of pyramids can be created by a container of toothpicks.  During the next "Acts," Dan asks the students how many levels can be created by 250 toothpicks, 500 toothpicks, and concludes by having the students write a function that relates the number of levels of the pyramid to the number of toothpicks.

Math in Three Acts by Dan Meyers are three part math tasks that engage students through thought provoking videos. The main question students engage with is "What's the probability of getting a yellow starburst in a package of starburst?" Students will think about what they information they need to determine this in Act 2. Student then predict the experimental probability based on the theoretical probability in Act 3.
