Beginning kindergarteners are introduced to science and engineering concepts through questions such as “What is a Scientist?” and “What is an Engineer?”, and go on to compare and contrast the two. They are introduced to five steps of the engineering design process and explore these steps using the “I do, we do, you do” set of guided instruction. At the end of the project, students produce a set of purple popsicles that they design using various materials and by following a set of criteria.

Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)
