Arithmetic Series
Fall for a series. Learners determine how to find out how far a skydiver falls in the first 20 seconds. The Algebra II instructional activity introduces the idea of adding up the terms of an arithmetic sequence. Pupils learn how to use...
Curated OER
Arithmetic Sequences
Find the sequence of an equation with your math super stars. They differentiate between arithmetic and geometric sequences and then calculate the sum of finite and infinite sequences.
Willow Tree
Fibonacci and Other Sequences
Fibonacci is an interesting sequence that forms some unique patterns. Learners explore sequences that do not have the typical arithmetic and geometric patterns. They identify the pattern and find the next consecutive terms....
Curated OER
Finding The Sum of an Infinite Series
Pupils examine finding the sum of an infinite series as the limit of partial sums. Through hands-on activities, students create their own sequence by finding the area of a square and then cutting it in half-sized pieces. They write out...
Curated OER
Skeleton Tower
Your algebra learners build a quadratic function in this task of counting the blocks used to build objects. The arithmetic sequence that shows up brings up a shortcut to the long addition using the Gauss Method. Eventually, learners...
Curated OER
Arithmetic and Exponents - Week 1
In this exponent worksheet, students add numbers written in exponential notation. They identify the base and the exponent. This two-page worksheet contains examples, definitions, and nine problems to solve.
Curated OER
Ws and Worms
Students explore problem solving strategies. Given real life problems, students examine the sum of consecutive strings of whole numbers. Students use diagrams and sequencing to solve problems. Students justify their mathematical...
Curated OER
Coin Exchange
Second graders explore the concept of money and simple arithmetic. They represent a sum of money using various combinations of coins and devise and use problem solving strategies to explore mathematical situations.
Curated OER
The Magic Squares
Fifth graders devise and use problem solving strategies to solve a magic square arrangement. In small groups they explore various strategies including non-algebraic and algebraic techniques, write an explanation of their solution, and...
Curated OER
Three Circles II
Fourth graders practice a variety of strategies when investigating what happens when they put various numbers into circles of a configuration: they express a fraction as a decimal, write and solve problems involving decimal...
