Mathematically:

• Addresses standards: 1.OA.C.6 and MP.5
• Uses the relationship between addition and subtraction to help students develop fluency with addition facts for standard 1.OA.C.6
• Builds on students' understanding of decomposing numbers in different ways
• Includes the use of tools (e.g., concrete models) to reinforce the conceptual understanding that anchors fluency (MP.5)
• Part of a carefully considered progression toward fluency and memory with single-digit sums

In the classroom:

• Allows teachers to choose targeted sums to tailor practice based on student need
• Builds fluency in an engaging way
• Offers multiple opportunities for students to practice their facts to ensure fluency

• Making the Shifts

How does this task exemplify the instructional Shifts required by CCSSM?

 Focus Belongs to the major work of first grade Coherence Develops fluencies that students will rely on in subsequent grades as they progress to full fluency with multi-digit addition and subtraction using the standard algorithm Rigor Conceptual Understanding: secondary in this set of tasks Procedural Skill and Fluency: primary in this set of tasks Application: not targeted in this set of tasks

Reaching fluency in addition and subtraction takes time and practice. Students will need many opportunities and varying activities to develop this fluency and practice should be incorporated into math instruction on a regular basis. Traditional approaches to teaching fluency tend to rely on worksheets that ask students to recall facts: these tasks illustrate a different type of practice that will also help students develop fluency. These two tasks are part of a larger set of tasks for grades K–High School from youcubed, and the full task bank can be found here.

These tasks may be modified as students are first developing fluency for addition and subtraction within 5 (K.OA.A.5), and as students continue to work toward fluency with sums and differences within 20 (2.OA.A.2). Teachers may further differentiate these tasks for their students by targeting specific sums and differences with which they see their students struggle.
