2nd grade students are expected to add and subtract to 1000 using place value strategies. This unit takes the first step toward that goal by subtracting 2-digit numbers within 100 with and without regrouping or unbundling. Students will use concrete, hands-on materials including linking cubes and place value disks. Additionally, students will use the representational model of drawing dots on a place value chart to add. Students will relate these models to a written method.
This set of 5 lesson plans creates a cohesive unit that will help your 2nd graders to build a solid foundation in subtraction with and without regrouping so that your students will feel confident when moving into larger numbers in the future.
This unit is included in a GROWING bundle! Although there are limited units now, the bundle will ultimately include 14 (!) units. As units are added, the price of the bundle will increase until it reaches the final price of $90. By buying now you will receive all future updates to the bundle for free!
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 3-digit number place value 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!
