Later in the year, after learning the standard algorithm for multiplication in unit 4, students solve problems involving volume with larger multi-digit numbers as side length measures. This progression increases
Previous research taught the standard algorithm; however, standards include using multiple strategies. Therefore, the purpose of this study was to use the CRA sequence to teach multiplication using another strategy, partial products algorithm. Three elementary students with disabilities participated in the...
By Grade 6, most students should be fluent in dividing multi-digit numbers using the standard algorithm. But no matter the grade, remind students that there are many ways to think about division, just like there are many ways to think about multiplication, and this algorithm is one tool to ...
It was a great way to revisit what we learned in that lesson, compare how different students showed their thinking, and reinforce the important idea that we can use multiplication to represent comparisons with the language “times as many.” After analyzing two student responses, we revisited the...
We note that any quadratic optimization problem has a natural relaxation to an SDP, in which we relax real variables to take vector values and we change multiplication to inner product: Figure 1: The hyperplane through the origin defines a cut partitioning the vertices into sets and . Solving...

themselves and solve the related problems” were 0.35 and 0.75, respectively, and for the ILO, which reads “Students will be able to express the divisibility rules of the number being in the form of a multiplication of two different primes, and solve related problems” were 0.25 and 0.90, ...
Semantic interpretation: Logarithm is actually a labeling and anti-labeling mechanism in power space. It establishes a new expression space, which makes multiplication operations converted into addition operations in this space, thus simplifying the handling of many mathematical problems. This transformation...
This second grade boy (My Son!) who had never been taught multiplication, what it means, or any algorithm for it, created a strategy for finding a solution to a contextual problem that most of us would solve using multiplication.Hecame up with the strategy. It was based onhisunderstanding...
