Math Resources

Pam Harris is a national author and presenter of how to effectively teach math to children. Recently she started a series of Podcast Episodes. This one is relevant for PreKindergarten and Kindergarten teachers.

Today we released episode #16 The Language of Counting. Parents and teachers of young learners, this podcast is for you! Kim and I talk about how to build meaning while kids are learning to count, how language can help, and what to do when language gets in the way of building meaning.

We also talk about some big teaching ideas that apply across all grade bands:

  • "just-in-time" vocabulary, where we build meaning first and then tag the socially-created name

  • using multiple representations to build robust understanding

I hope you are enjoying listening to Kim and me talk about math and teaching math. We are having a lot of fun making each episode. If you have questions or topics you would like us to discuss on the podcast, reply to this email or contact me through Facebook or Twitter. See you on #MathStratChat on Wednesday! Thanks, and have a great week.

Count from 1 to 100 by 1's with the coolest counting DJ around and Jack Hartmann.
Subitize to 10. Subitize is the ability to tell the number of objects in a set, quickly, without counting. Subitizing develops math fluency, when students recognize sets without having to count each object and it helps develop number sense and the ability to perform mental math.

WHAT PARENTS NEED TO KNOWParents need to know that Bedtime Math provides a daily math problem for different age groups, generally pre-K, K–Grade 2, and Grade 2 and up, although specific ages aren't listed. The site's intent is to make math a regular occurrence for families. Answers are included, so kids won't get too frustrated if they can't figure a problem out; parents may want to read the problem to their children to make it more challenging. Kids can share items on social media but can't interact with others on the site; for additional information on the site's use of personal information, be sure to check out its privacy policy.

New Web-based Tool for Early Childhood Educators and Families

The University of Denver’s Marisco Institute offers a free resource for teachers, home visitors, and parents to support learning in mathematics for young children beginning with infants and toddlers. It includes online games, printable materials, and other supports for learning at home. The site also provides professional development resources. Especially important is that [LT]2 helps early childhood educators to learn about how children think and learn about mathematics and how to teach mathematics to children up to age 8.

Teachers, home visitors, and parents have access to information about Learning Trajectories for math and to hundreds of classroom and home activity ideas to support children's development along the math trajectories.
