This video illustrates how to use the traditional algorithm to solve subtraction with regrouping. The traditional algorithm focuses on digit placement and requires that students move right to left to correctly perform the operation. Before students are introduced to the standard addition algorithm, it is important that they have a conceptual understanding of regrouping. This will allow students to correctly use the algorithm when they exchange 10 ones in the ones place value column with 1 ten in the tens place value column.

This video demonstrates how to use the lattice division strategy. The lattice division strategy eliminates the requirement to use automatic recall of facts, such as in the partial quotient strategy, but this strategy requires that students follow a very specific set of steps. Careful use of the lattice is required. The lattice strategy partitions numbers into smaller parts and it may not be an efficient strategy for students to use if they do not understand how division works.

This video demonstrates how to use base-10 blocks and a place value chart to help students add numbers that require regrouping. The use of direct modeling with concrete manipulatives, such as base-10 blocks, allows students to develop conceptual understanding of mathematical operations before attempting addition problems without materials or counting strategies. When students are provided with multiple opportunities to use manipulatives, they develop an understanding of how regrouping works.

This series of videos provides brief instructional examples for supporting students who need intensive instruction in the area of place value computation. Within college- and career-ready standards place value is taught in K through Grade 5. These videos may be used as each concept is introduced, or with students in higher grade levels who continue to struggle with the concepts. Special education teachers, math interventionists, and others working with struggling students may find these videos helpful.

This video illustrates the use of scaffolding with manipulatives to teach students to group objects by tens with counting by ones.  When students practice counting numbers greater than 10 with manipulatives, they learn to recognize the patterns in place value and they begin to think about sets of 10 objects as one unit. Students develop fluency in counting by ones, and then counting by groups of 10 and ones. Once that skills is mastered they are ready to practice opportunities to count by tens and ones to determine cardinality (i.e., the total amount of the set). 

Supporting students with math difficulty can be challenging. When teaching students with math difficulty, it is important to provide explicit and systematic instruction, teach math vocabulary and symbols, use the concrete-representational-abstract framework, and incorporate fluency building, effective questioning and error analysis.

This series of videos provides brief instructional examples for supporting students who need intensive instruction in the area of numeracy and counting. Within college- and career-ready standards numeracy and counting are taught in Pre-K through Grade 1. These videos may be used as each concept is introduced, or with students in higher grade levels who continue to struggle with the concepts. Special education teachers, math interventionists, and others working with struggling students may find these videos helpful.

Question: What should we consider when teaching students with math difficulty? 

Implementing intensive intervention to improve outcomes for students with significant learning and behavior needs is challenging work! In this webinar, panelists share lessons learned from five years of implementing intensive intervention at the district and school level. In this webinar, Dr. Rebecca Zumeta Edmonds, Deputy Director of NCII, Dr. Chris Lemons, Senior Advisor to NCII and Assistant Professor in the Department of Special Education at Peabody College of Vanderbilt University, Dr. Kim Moore, NCII district coach for Columbia Public Schools in Columbia, Missouri, Dr.
