Thursday 'Rithmatic: Number of the Week

Calendar math is a huge part of my classroom. It's a user-friendly way to share math concepts without overwhelming or intimidating students. My calendar math board is subject to a variety of adaptations throughout the year, but one of my favorite features is the Number of the Week.

Each week has a given number. (1, 2, 3... you get the idea.) Students have a number of the week journal (coming soon to my TPT store!) in which they can record the Number of the Week activities each day as we do them together in class. It goes a little something like this:

• Monday: Record the numeral and the written number. (Ex: 1, one)
• Tuesday: Fill in a ten frame to represent the number.
• Wednesday: Represent the number using tally marks.
• Thursday: Draw a picture of the number. (Ex. 1--one circle, 2--two squares, etc.)
• Friday: Review as a class--no notes needed.

The slow, involved approach gives students ownership of each number without resulting in an overwhelmed panic. As an added plus, the Number of the Week journals can be collected as often as you see fit for a quick assessment of student learning. It's a simple and effective element for any calendar math routine!

Keep it class-y, ya'll.

CCSS Math.Content.K.NBT.A.1. Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
