Welcome to Monster Math Counting and Number Lines! The first math concept that your students must acquire is a sense of numeracy. Developing a sense of numeracy begins with sorting and counting objects. This resource includes lots of practice with counting by one, five, and ten, and counting on and counting back. It also introduces practice using a number line and the 100 and 120 charts. It is appropriate for kindergarten or early first-grade practice. This packet is aligned with the Common Core Standards and with the TEKS. It allows students to practice the skills that are required for mastery of the standards. It also provides a rigorous path that leads students into the next levels of learning.

The unit includes guided and independent practice for each concept. For each topic, there are at least two colorful guided practice/re-teaching pages designed for projection or for small group intervention. Also included for each concept are ten printer-friendly (less graphics) pages for independent practice, to use for small group work or centers. Use part or all of this resource to help your students develop number sense. The pages print equally well in black and white and in color.

I have used guided math in my classroom for over ten years. I begin my teaching time block teaching/spiraling math concepts as a whole group, but most of my math block is devoted to guided practice in small groups followed by independent or small group practice, centers and intervention. I begin my math time every day with a page from my popular Number of the Day series. You may find more math in this “printable” format in my store.

I hope that you and your kids enjoy this great bundle! Check back soon. I continue to add Number of the Day units daily!
