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. It is important for students to know and understand how to use the traditional algorithm because it is an efficient strategy to use if regrouping is required, when numbers have varying numbers of digits, and when the numbers included are too large to reasonably use other strategies (e.g., partial differences can become confusing for students who do not understand negative integers).

This video demonstrates how to use base-10 blocks and a place value chart to help students subtract multi-digit numbers that require regrouping.
This video demonstrates how to use base-10 blocks to help students solve multiplication problems that cannot be solved with automatic retrieval.
This video shows how to use an area model to solve a multi-digit multiplication problem. An area model can serve as a visual representation of the partial products multiplication strategy. Using an area model may be a good option for students who have not yet gained a conceptual understanding of how regrouping works or how the partial products strategy works. The area model method can serve as a visual guide for students until they are ready to use traditional algorithms.
This video demonstrates how to use base-10 blocks to help students solve division problems that cannot be solved with automatic retrieval. The use of direct modeling with concrete manipulatives to demonstrate division allows students to visualize the division of a quantity into equal groups. Students should have multiple opportunities to practice division with manipulatives to develop an understanding of the steps for regrouping and dividing quantities into equal groups. While students may have moved on to traditional algorithms with other operations (e.g., subtraction) they may still require the use of concrete manipulatives with learning division.
This video illustrates the use of scaffolding with manipulatives to teach students to group objects by tens with counting by ones.
In this video, Drs. Mitch Yell and Tessie Bailey share information about the 2017 Endrew F. v. Douglas County School District decision by the U.S. Supreme Court. They highlight implications for writing a student's IEP and discuss the importance of setting setting ambitious IEP goals to ensure that students make progress in light of their individual circumstances.
This video demonstrates how to use fraction tiles to explore how fractions such as 4/4 are equivalent to 1. Before fractions are introduced in the curriculum, students use integers, which only have one value associated with the numeral or number word. Fractions may be the first time that students are introduced to the possibility that the same quantity can be represented with different representations, such as one whole and four fourths. Using models allows students to practice finding equivalent fractions, which is a prerequisite skill for performing computation with fractions.
How might MTSS affect what's measured on report cards, including academic and non-academic measures?
In this video, Dr. Rebecca Zumeta Edmonds, Co-Director of NCII, discusses ways that a multi-tiered system of supports (MTSS) can help educators consider what student report cards can measure beyond academic performance.
In this video, Sandy Cook, NCII Coach and Differentiated Instruction Specialist at Elms Road Elementary in Swartz Creek Michigan & Michele Corbat, NCII Coach and Principal at Morris Elementary in Swartz Creek Michigan, discuss the importance of leadership to support implementation of intensive intervention.
