2nd grade students are expected to mentally find 10 and 100 more and less using place value principles. This set of 5 lesson plans creates a cohesive unit that will help your 2nd graders to build this understanding.

Your students will use an abundance of hands-on materials along with place value drawings and place value charts in order to develop and demonstrate their understanding of how to compare numbers based on place value.

This unit is included in a 2nd Grade Math Intervention Bundle! Support your students throughout their 2nd-grade year in order to close the gaps in understanding and prepare them for success in their 3rd grade year.

Need the flexibility to teach digitally or face-to-face? This unit can also be purchased as a DIGITAL & PRINTABLE resource so that you can seamlessly switch between in-person and online teaching.

This intervention resource is designed to support you with everything you will need in order to intervene for struggling learners who have not yet developed an understanding of how to find 10 more 10 less 100 more or 100 less in the whole group setting with their peers.

Included you will find:

Overview and Organization

The 5 Day Focus resources are designed to be informative and easy to use. I have included an overview of the related standards, an outline organizing the breakdown of how the topic is taught, a table of contents and a page outlining any and all materials that will be needed. I want you to be able to spend your time and energy on looking at your students' results and reflecting on their learning- NOT on organizing materials and trying to figure out how to use this resource!


Pre and Post Assessment Materials that mirror one another will allow you to see where your students began and how far they have progressed. I have also included daily exit tickets and a tracking form so that you can easily monitor each of your students. 

Direct Instruction

Instructional lesson activities to use with small groups or individual students. Each of these lessons is detailed and includes hands-on activities. There is gradual release across the 5 days beginning with more concrete models and moving away towards representative and, finally, abstract models. This research-based progression will surely help your students to progress. 

Independent Centers

Each of the 5 lessons also includes an independent practice activity. The independent activities have been created in the style of math centers so that they can be used directly after the instructional lesson but so they can also be used and re-used as students practice their skills.

And remember, follow my store so you will be updated when new resources are added! I list many products on sale for the first 24 hours!
