PORTRAIT OF A LEARNER SPOTLIGHT
Math Night at Newington Public School took parents on a journey through Place Value Through the Ages, showcasing how we help our students think about numbers and build a strong mathematical foundation.
Math night focused on understanding numbers—beginning with something as fundamental as counting— understanding counting is a complex and dynamic process than it may seem. Research over the last 20 years suggests that the early stages of counting in young children are often complex and, at times, a bit messy. But that’s part of the beauty of learning! To truly understand numbers, students must grasp the abstract nature of what a number represents—a property of a group of objects, not just a symbol on a page.
Our goal at NPS is to cultivate a deep understanding of these concepts in our students, preparing them for future problem-solving and critical thinking. As John Hattie once said, “A close association between a previously learned task and a new situation is necessary for promoting transfer of learning.” This insight guides our work as we strive to build on students’ existing knowledge and help them make connections that deepen their understanding.
Math night left families with a greater appreciation for how place value and number sense are taught at NPS, and with a sense of how important these early steps are in the mathematical journey.
STUDENT HIGHLIGHTS
Famous children's author, Chris Van Dusen, visited SAU 50 and WOW, what a treat! Most notably, Chris has written The Circus Ship and the Mercy Watson series. He amazed us with the stories of how he writes his books. He shared that he drew the lobster on the Maine license plate and uses the L.L. Bean catalog for inspiration. He was so fascinating! Rye Elementary School had all students from New Castle and Newington come for the event before Chris ventured over to Greenland Central School. He signed children's books and was a pleasure to host in our district. We can't wait for his next book!
