FirstieMath® Unit Nine: Numbers to 40

This unit is part of my larger FirstieMath® bundle! Click HERE to view the bundle!

What is FirstieMath?

FirstieMath Curriculum is a First Grade Math curriculum set of units and are teacher created, kid-tested, and most importantly kid-approved! FirstieMath takes away that monotonous way of teaching math where students sit and listen to the teacher TEACH math. Instead, FirstieMath encourages guidance from the teacher while the students TEACH and LEARN math through hands-on and engaging math activities with their partners. FirstieMath units are made of of 10 instructional days each unit but can be adjusted to fit your classroom needs. The units include a pre and post test as a way to ensure student growth over the unit. FirstieMath units also SPIRAL learning constantly! They do not teach the concept and then it behind. We will continue to review those previously taught skills! These are just a few highlights you’ll see using the FirstieMath Units; kids talking about math, kids using manipulatives, activities that are fun + engaging, learning that requires critical thinking!

What is the Scope and Sequence of FirstieMath?

FirstieMath Curriculum is a 30 week math curriculum that includes lesson plans that include breaking down a 60 minute block math time into these sections {whole-group number sense, whole-group fluency, whole-group math lesson, collaborate lesson follow-up aka pair work, and independent practice aka worksheet}. The units will also include any and all cards needed to make the lessons successful! You will just need to provide the manipulatives like teddy bears or snap cubes!

FirstieMath Curriculum is a simple print and teach math curriculum. No more tracking down ideas, worksheets, cards, etc! I have it covered!

What is included in FirstieMath?

-Teacher "simple read" lesson plans. You will not need to rewrite these lesson plans, unless you choose do. If so I have included editable lesson plans.

These worksheets were exactly what I needed for my students! The layout was clear, age-appropriate, and easy to follow. I loved how the content aligned perfectly with our current standards, and my students stayed engaged throughout the activity. It worked well for both independent work and small group review. Highly recommended!
