# Ideas for Counting During Primary Math Activities

Learning to count is more complex that you might expect. As described in the Collaborative’s book Big Ideas of Early Mathematics, there are two different types: rote counting and rational counting. While both are useful, “when young children develop rational counting skills they are armed with a tool that enables them to understand the concept of numerosity, to compare quantities of different sets, and eventually to engage in operations. Rational counting is a foundation for children’s early work with numbers.”

This link delves into some ideas for exploring counting as well as building those primary math activities into opportunities to investigate numerosity and patterns. While it is always a good idea to encourage all kinds of counting throughout the day, there can be times teachers and parents are able to use those moments to build deeper foundations.

# Algebraic Thinking with Shoes

Cindy Collado and her preschool class at Stock School were involved in a shoe project that incorporated many math concepts through a variety of activities over the course of two months. The class started by taking a good look at their shoes and then talking and thinking about what they saw.

# Control Your Math Fate, Estimate!

Ellen Stoll Walsh's book Mouse Count can be used in the classroom to cover such broad-ranging topics as data analysis, number sense, and number and operations. Key concepts such as estimation can be explored and investigated.

# Down with Naked Numbers

All kinds of confusion can result when children are asked to rattle off the numbers from 1 to 10 or 20 or higher without actually counting something. In our learning labs and activities we are working to help teachers find ways to avoid “Naked Numbers
