Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–4 Professional Commentary: Students discover the rule used to sort numbers into two sets -- those numbers that belong according to the rule, and those that don't belong. Without revealing the rule, students can show that they have discovered the rule by correctly categorizing numbers proposed by their classmates.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: This lesson focuses on patterns that can be interpreted in more than one way. Students look at sequences and sets that have more than one defining characteristic (e.g., Ann, Brad, Carol, Darius) and describe the various rules that could determine the next element.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 7–8 Professional Commentary: This lesson integrates ideas from geometry, measurement, and algebra. Students measure the length and width of a rectangle using at least six different standard and nonstandard units of measure.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 5–7 Professional Commentary: In this lesson, students explore the Fibonacci series. They identify the pattern among the Fibonacci numbers, look for applications of these numbers, and explore the ways that this pattern can be related to objects and shapes in both the natural and designed world.... 5 Multiplication: It's in the Cards 3: More Patterns with Products Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: This lesson is the third in a 4-lesson unit on introductory multiplication. Students use a sieve of Eratosthenes applet to study multiples of any number and look for patterns in the multiples.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 5–8 Professional Commentary: Exploring the relationship between two variables prepares students for the study of functions, which in turn provides the basis for much of the study of algebra. Students work in pairs to measure their arm span and height and record them on a class chart.... 7 Patterns That Grow 3: Growing Patterns Resource Type: Lessons Discipline: Mathematics Grades: Grades 3–5 Professional Commentary: Students learn about growing patterns by first replicating some growing dot patterns and then creating their own. They go to the Math Forum website to learn about a famous growing pattern, Pascal's triangle.... Resource Type: Lessons Discipline: Mathematics, Science Grades: Grades 3–6 Professional Commentary: Students use the ingredients of fruit salad to establish the foundation for proportional reasoning. Students are introduced to proportional reasoning through modeling, sharing, and questioning techniques.... Resource Type: Lessons Discipline: Mathematics Grades: Grades 4–5 Professional Commentary: Students explore and find rules for a growth pattern in snakes. The teacher presents students with rules for a growth pattern that involves red and black rings in imaginary snakes.... 10 Rectangle Pattern Challenges Resource Type: Lessons Discipline: Mathematics Grades: Grades 5–9 Professional Commentary: Students analyze three stages of a colorful rectangular pattern, and then determine the composition of future stages. Younger students can describe in words how the pattern grows, while older students can find algebraic expressions for the number of blocks of each color in the pattern.... |
