When we talk about math we often talk about problems, equations and formulas. But behind the numbers and symbols, math is a way of thinking and exploring relationships. Factual knowledge about numbers is important, but far more valuable is the understanding of what numbers represent and how they relate to each other. This understanding, number sense, is the foundation for more complex mathematical concepts. From kindergarten through fifth grade, Lower School Math Specialist Mrs. Stacy Shaener teaches daily explorations of number relationships that get the whole class cheering about math.
Routines Are a Good Thing
Number routines are intentional daily exercises to reinforce and develop number sense. Number sense includes understanding quantities, more and less, larger and smaller, order, symbols as representations of concrete objects, and more. A student can memorize that one plus one equals two. But without good number sense, they can’t understand that adding one more to that group makes three. Number routines are a very effective way to get students thinking and talking about these types of relationships.
“I love using these because every student can participate with the group but at their level. Differentiation for varied learning abilities is built in. These routines encourage students to practice reasoning and mental math, and to use mathematical vocabulary in a very natural way. They learn to talk about their thinking and listen to others at the same time.” — Mrs. Shaener
Same But Different
In this routine, Mrs. Shaener posts two sets of numbers or number relationships on the board and asks the class to list everything that is the same and different. Rather than ask students to solve for a specific answer, she asks them to consider anything they might know about these numbers and how they relate to each other. Mrs. Shaener asks her students to justify their responses. They have to explain their thinking and through that process can often discern if they’ve made a statement that doesn’t make sense.

In this number routine, Mrs. Shaener shows the class an image and asks them to wonder what number it represents. As students make their estimates, she reveals clues that help them narrow the choices down to a smaller and smaller set of numbers, until the big reveal at the end. After each clue, Mrs. Shaener asks the class to talk in small groups about their thinking.As students make estimates about the number of objects in the photo, she asks them to use what they already know about numbers. For example, a student suggested 100 for a small group of rings. Mrs. Shaener asked if they thought 100 was a big or small number and then directed them to look at the picture again. The student was able to quickly self-correct and make a better estimate after thinking about that relationship. Click here for more about esti-mysteries from Steve Wyborney.
Having a Blast Learning Math
These are just two examples of the many number routines Mrs. Shaener uses with her students. You can feel the energy in the room when they practice them — there is a buzz of excited chatter as students raise their hands high into the air. With encouraging dialogue, Ms. Shaener teaches her classes to celebrate successes, work through struggles together, and see that process is the most important part of learning math.

Support for our Students at Every Level
We are committed to meeting the individual needs of a diverse group of learners at Severn and believe that children do best when they have a committed team of adults supporting them. Mrs. Shaener helps our Lower School students make math a priority, while also making it fun. Through professional development workshops and research, she keeps up-to-date on new and better ways to engage our kids in authentic problem-solving activities and works closely with teachers to keep every student moving forward with confidence in math.
