Family Math Night

Part I: Activity Details

For our Family Math Night activity, we will help students understand and have fun with

probability by exploring with colors and spinners. We will have three large spinners for the

students to watch. These spinners will be used to help the students fill out their worksheets

(*Attached). This activity will be engaging and exciting for parents and students because it is

very hands-on and fun to learn about. This activity involves bright colors to draw students

attention. For some of the younger students they may have yet to learn about probability so

our activity will offer something new, and hopefully fun for them to get a jump-start on.

Students will also have fun guessing what color the pointer will land on next. They will be

more than excited when they get the answers correct, especially because probability is based

on chance. Once they have completed the activity and gotten our stamp of approval, students

will be given a Ziploc bag full of materials to take home and make their own spinner. This way,

the students are able to practice and play with probability with their families.

For Kindergarten and 1st grade students, their circle will be split into 3 segmented areas and

each segment will be a different color and different size. By making them drastically different

sizes, we believe it will be easier for students to understand probability concepts. For our

project we are looking for students to understand, the larger or more of an object compared to

the others, the more likely to be chosen. Students in grades 2 and 3 will be working with

another spinner; their spinner will be split into 7 different size segments, colored separately,

and each segment will be numbered this time, to add to the concepts. For 2nd and 3rd graders,

probability is still relatively new, so we made different sizes again to develop the concepts

stated above. Adding the numbers also gives another factor, fractions. The numbers were

placed randomly on segments and students were asked to predict what number the spinner

would land on the least. We were hoping students would add the segments together to realize,

for example, there might only be one “2” segment on the circle, but when adding the two “3”

wedges they are still smaller than the one “2” wedge, so they should expect the spinner to land

on one of the “3” segments the least. Finally, students in the 4th and 5th grades will be

learning with a circle with 8 segments of the same size, and those will be different colors and

numbered as well. For the older kids, their circle, of 8 segments, will be the same width to

make it more challenging for them. By now students will have been introduced to probability

and some of the concepts, so by making them the same size wedges we are hoping to solidify

how the amount or size of the object affects how often it is chosen.

Since there are three of us in our group, each of us will be in charge of one spinner and be

helping out the corresponding age group. We will be spinning the large spinners for the

students. While we are doing so the students will be filling out their grade specific worksheets.

The worksheets will include a prediction section, a tally box for them to record the data, as well

as some questions to answer when they are done.

Before beginning this activity, students will need to understand probability, or at least have

an idea of the concepts. They will also need to know a little bit about fractions and ratios to

help them answer questions correctly. Ratios will also help them to understand better about

how the probability wheel works. If students are unsure of what we are doing, we will simplify

the concepts. For example, we could ask them, “If we have a bag of six blue and four red

marbles, which color are we more likely to pick out?”

Based on the information given, we believe students in 3rd, 4th or 5th grades would be

more apt to understand this activity. This is because, by this age they will have started working

on the concept of probability, so the activity will be easier for them to pick up on. Even though

K-2 will not have had experience with probability in the classroom, with a little guidance they

should not have any problem picking up on the idea.

Part II: Standards & Modifications

Common Core State Standards (CCSS) for Mathematics:

3.NF.1: Number and Operations – Fractions

- Understand a fraction 1

𝑏 as the quantity formed by 1 part when a whole is

partitioned into b equal parts

- Understand a fraction 𝑎

𝑏 as the quantity formed by a parts of size

1

𝑏

This CCSS aligns with our activity because our spinners have wedges that are fractions

of the whole circle and we are trying to get students to understand that in a fun,

colorful way. For our students we want them to understand a bigger slice, or

fractions, results in a greater chance of being chosen. For many of the students we

worked with they were able to understand quickly the concept of a larger piece of the

circle created a larger area to land on.

National Council of Teachers of Mathematics (NCTM) Process Standards

Representation

This process standard describes representation as the need for alternate ways of

demonstrating math is crucial for understanding. We believe this fits our activity best

because we are incorporating the idea of fractions into our project as well as

probability. Each section of the spinner represents part of the whole and therefore is

a fraction of the piece. This is another way for students to see how fractions work.

Common Core Standards of Practice

Model with Mathematics

This standard of practice is described as being able to apply the math concepts they

already know to everyday-life. Younger students will be able to apply what they learn

in our activity such as the larger the amount of one object the more likely it is to

occur, as well as everything is based on chance when thinking about probability, to

their assignments in high school. Once they graduate they can use the concepts of

probability and ratios to the real world. For example, probability is used in sports,

when determining the likelihood one team will beat another based on previous

statistics; and even the weather, the weather channel has very much to do with

probability, they tell you how probable it is to have rain in the forecast.

Part III: Modifications

Since we will be working with students from Kindergarten through fifth grade, our activity

will need to be adjusted to fit all their needs. For each age group we will have different large

spinners tailored to their education level: Kindergarten and 1st grade will have a spinner with 3

different colored and different size segments; 2nd and 3rd graders will be working with a

spinner with 7 numbered and different color segments of various sizes; and students in 4th and

5th grade will have a spinner with 8 numbered and different color segments of equal size. The

students will also have their own worksheet for their grade level. In K-1 the worksheets will be

fairly simple, they will consist of a tally box and a few questions about why the spinner landed

on a certain color the most. For 2-3 students will also have a number tally box with the color

box and similar questions as K-1. They will additionally have questions about the numbers too.

Their worksheets will also have a conclusion question about what the size of the wedge

determines about probability. Students in 4th and 5th grade will have the same questions as 2-3

but they will have more colors and numbers to work with.

For younger students we have altered the spinner to make the answers more obvious by

making the segments drastically different sizes. And the older students will have a spinner with

equal segments to make predictions more difficult as well as make the students think more

about how probability changes if the segments are equal or different sizes. As previously

stated, each of these differences will help to challenge the students.

Part IV: **Attached

Part V: Data Collection

Question 1 (Mathematical Content): How many students were able to make the

assumption, the larger the wedge the more it will be landed on?

Question 2 (Mathematical Processes): How many students related the spinner wedges to

fractions of the whole spinner?

For both of these questions we will observe how students work out loud through the

questions as well as how they answer the questions on the worksheet to collect data.

Part IV: Data Analysis & Reflection

We had a blast at Family Math Night; it was fun to interact with the students and their

families. We enjoyed working with students on math concepts and furthering their

understanding. We had a lot of 2nd and 3rd graders than other grades. We had very few 4th and

5th grade students. All students seemed to have fun and enjoy learning. The parents that

helped, you could tell were very involved with their child’s learning and they were very

encouraging.

After reviewing the night we determined, according to our content question, most of our

students were able to make the assumption the larger and area the more likely it is the spinner

will land on that wedge. Some of the older kids came into the activity knowing that but some

of the younger students learned that after doing our activity. So we were very glad to see we

were able to reinforce that concept to students. The other question we asked, however, based

on the processes, we did not have any students say, out loud at least, they saw the wedges as a

fraction of the whole spinner. Unfortunately we were not able to see students make that

connection overall as well as apply it to their prediction of what number the spinner would land

on the least as we had hoped. But hopefully they will be able to take that experience and use it

again in their classes when they start learning about it.

We were very prepared for the educational level of students, our questions and spinners

seemed well made for grade levels. If we were to do it again, we would probably have other

examples of probability there, like the marble example. It would have been easier if we had

those there. Other than that everything went smoothly and we only had to do a little

explanation to get them through.
