This video illustrates how to use the traditional addition algorithm with regrouping.
These three videos highlight key resources available to support families of students with the most intensive needs at home and as they transition to and from in-school services during the COVID-19 pandemic. The videos speak directly to parents and recommend that parents share the videos (and the mentioned resources) with the team of educators and other professionals working with their child. An easy-to-share handout is included for each of the videos. These handouts identify and link the spotlighted resources that educators and parents can turn to in planning for and supporting children’s virtual learning or return to in-school learning.
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 illustrates the use of manipulatives to help students integrate the concept of counting by ones with skill in grouping by tens.
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 reviews to how use the traditional algorithm to solve multiplication with regrouping.
This video illustrates the use of finger counting to count by tens and ones.
This video illustrates the use of manipulatives to help students develop fluency in counting by tens and ones.
