Data fun!

November 11, 2020 | Ms. Jonker

For the past few weeks, we’ve been learning about data. Students have practiced collecting, graphing, and analyzing data. This unit began just as we were beginning our two weeks of remote learning. In spite of that, the students started out strong. They mastered attaching photos to Google Classroom and were able to send me photos (and videos) of the line plots they were creating.

One of the trickiest concepts we’ve covered during this data unit is creating a scale along our line that will fit the entire range of our data. I observed students using strategies like rounding and skip counting to successfully create their number lines.

Graphing the data is the fun part, and then comes the analysis. Students have been learning to identify clumps, highest/lowest values, outliers, and range. They have also been writing about what these different landmarks in the data tell us about the data set.

Now we are halfway through our own data investigations. Students have reached out to all of the fourth graders for numerical data about data questions they created. Students will compare two data sets: Adventurous and Courageous.

Students will graph, analyze, and present their findings. I am excited to see what they come up with! After Thanksgiving we will circle back to multiplication and also begin a division study.

Kat Jonker

Teacher, Grades 4

Kat Jonker is energized by how passionately Mustard Seed School nurtures each student to blossom into the person God has made them to be. She’s honored to teach and learn beside the fourth and fifth grade students here.

Ms. Jonker’s always been surrounded and inspired by dedicated teachers--including her mother! When she began teaching private violin lessons as a high school student, Ms. Jonker began to think about teaching as a career. Soon she realized her passion for teaching and learning as an Elementary Education with an integrated science major at Calvin College. There she flourished as an assistant teacher at Calvin’s middle school chemistry camp. She also led elementary nature programs at Calvin’s ecosystem preserve.

Music remains one of Ms. Jonkers passions and you’ll sometimes get to hear her playing in worship. She’s an avid violin player and spent a disproportionately large amount of her college life in string quartet rehearsals. She listens to music constantly and likes to keep it eclectic, so if you have any music recommendations, send them her way.

Grand Rapids, Michigan, is Ms. Jonker’s home town. Through God-gifted communities of faith there, she found her roots in grace and a life of service.
