Essential Understandings
Concrete:
- Make a set of base ten blocks that represents a two-digit number.
- Subtract a set of base ten blocks that represents a multiple of 10.
- Recount the set to get a difference.
- Make a visual representation of base ten blocks that represents a two-digit number.
- Subtract a visual representation of another set of base ten blocks that represents a multiple of 10.
- Recount the set to get a difference.
- Understand the following concepts and vocabulary: subtract

Cluster:
Use place value understanding and properties of operations to add and subtract. (Major Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
Access Point Courses
- Grade One Mathematics (#5012030): The benchmarks in this course are mastery goals that students are expected to attain by the end of the year. To build mastery, students will continue to review and apply earlier grade-level benchmarks and expectations.
- Access Mathematics Grade 1 (#7712020): Access Courses:
Access courses are for students with the most significant cognitive disabilities. Access courses are designed to provide students access to grade-level general curriculum. Access points are alternate academic achievement standards included in access courses that target the salient content of Florida’s standards. Access points are intentionally designed to academically challenge students with the most significant cognitive disabilities.
- Foundational Skills in Mathematics K-2 (#5012005): This course supports students who need additional instruction in foundational mathematics skills as it relates to core instruction. Instruction will use explicit, systematic, and sequential approaches to mathematics instruction addressing all strands including number sense & operations, fractions, algebraic reasoning, geometric reasoning, measurement and data analysis & probability. Teachers will use the listed benchmarks that correspond to each students’ needs.
Effective instruction matches instruction to the need of the students in the group and provides multiple opportunities to practice the skill and receive feedback. The additional time allotted for this course is in addition to core instruction. The intervention includes materials and strategies designed to supplement core instruction.
