Description
Help students practice adding and subtracting scalar multiples of matrices with this 15-card deck. Students first multiply matrices by given scalars, then combine the resulting matrices by adding or subtracting corresponding elements. This deck reinforces multiple skills at once—scalar multiplication and matrix operations—while helping students stay organized through multi-step problems. The interactive format makes it ideal for Algebra 2 or Precalculus, whether used for independent practice, math centers, review, or formative assessment. The fill-in-the-blank format encourages students to focus on each individual entry, reinforcing accuracy and understanding of how scalar multiplication affects every element in the matrix. Problems include a variety of matrix sizes and positive/negative scalars to build fluency.
