Watch real teachers make the instructional Shifts. The Teaching the Core Video Library is a free, searchable database of bell-to-bell lessons that are annotated to highlight moments of exemplary Common Core-aligned instruction. Lesson videos include: the lesson plan and materials, example student work, an interview with the teacher, descriptive annotations that identify specific CCSS lesson elements, and annotations by educators using the Instructional Practice Guide.

Teaching the Core
Task Instruction
- In this activity each child has the same number of cubes and a cup.
- They take turns hiding some of their cubes in the cup and showing the leftovers.
- Other children work out the answer to the question “How many are hiding,” and say the full number combination.
Example: I have 10 cubes and I decide to hide 4 in my cup. My group can see that I only have 6 cubes. Students should be able to say that I’m hiding 4 cubes and that 6 and 4 make 10.
Snap It
Students work together to make different number combinations for a given number.
Material
- 10 or more snap cubes per student
Task Instruction
- This is an activity that children can work on in groups.
- Each child makes a train of connecting cubes of a specified number.
- On the signal “Snap,” children break their trains into two parts and hold one hand behind their back.
- Children take turns going around the circle showing their remaining cubes.
- The other children work out the full number combination.
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. For more on how students can gain fluency in addition and subtraction in grade 1, read pages 14–17 of the progression document, K Counting and Cardinality; K–5 Operations and Algebraic Thinking.
