Math manipulatives are physical objects that help students to understand abstract mathematical concepts by providing a tangible representation of those concepts. By using math manipulatives, students can visualize mathematical concepts and develop a deeper understanding of them. As a teacher, it is important to have a variety of math manipulatives at your disposal to make your lessons more engaging and effective. In this professional learning activity, we will explore various math manipulatives that can be used to enhance elementary math lessons.

This learning video introduces students to the world of Fractal Geometry through the use of difference equations. As a prerequisite to this lesson, students would need two years of high school algebra (comfort with single variable equations) and motivation to learn basic complex arithmetic. Ms. Zager has included a complete introductory tutorial on complex arithmetic with homework assignments downloadable here. Also downloadable are some supplemental challenge problems. Time required to complete the core lesson is approximately one hour, and materials needed include a blackboard/whiteboard as well as space for students to work in small groups. During the in-class portions of this interactive lesson, students will brainstorm on the outcome of the chaos game and practice calculating trajectories of different equations.

Using an Arduino microprocessor, students will build an automated fish food feeder so fish can be fed when no one is at school?

This project involves learning how to do simple wiring of an LED, a buzzer, and a servo (motor) to a simple-to-use Arduino microprocessor.

Material Description

This resource is a financial calculator that students may use in a finance portion of a mathematics class, a mathematics portion of a business or finance class, or wherever the user may find it useful.

The calculator can find future value and payment/deposit amount of a savings annuity. It can also find present value and withdrawal/payment amount of a payout annuity/loan.

Context for sharing:

The calculator allows students to more quickly solve contextual problems related to personal finance including loans, investments, and amortization, which provides more instruction time for deeper contextual problems.

Additional information about the resource:

The calculator is written in python, hosted by Streamlit, and may be copied and remixed through Github.

Students will use their knowledge or availability and scarcity to determine income and earnings.

An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using only a compass and straightedge. The method used involves constructing the perpendicular bisectors of two random chords. The bisectors intersect at the center of the circle. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This learning video presents an introduction to the Flaws of Averages using three exciting examples: the ''crossing of the river'' example, the ''cookie'' example, and the ''dance class'' example. Averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, however, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. During this video lesson, students will learn about three flaws of averages: (1) The average is not always a good description of the actual situation, (2) The function of the average is not always the same as the average of the function, and (3) The average depends on your perspective. To convey these concepts, the students are presented with the three real world examples mentioned above.

With this activity students get the chance to have casual conversation in the warm up, about their favorite sports teams, players and influential commercials. The main activity is centered around numerical signs, getting familiar with different types of measurement (time, amount, etc.)

The football team's bench fell apart at the game. We need to design and build a prototype for a new bench using the properties of congruent triangles and/or parallel lines.

Match shapes and numbers to earn stars in this fractions game. Challenge yourself on any level you like. Try to collect lots of stars! The main topics of this interactive simulation include fractions, equivalent fractions, and mixed numbers.

This resource was created by Judy Prewett, in collaboration with Dawn DeTurk, Hannah Blomstedt, and Julie Albrecht, as part of ESU2's Integrating the Arts project. This project is a four year initiative focused on integrating arts into the core curriculum through teacher education, practice, and coaching.

Demonstration/Focus Lesson on how to understand fraction of a set by using manipulatives

Explore fractions while you help yourself to 1/3 of a chocolate cake and wash it down with 1/2 a glass of orange juice! Create your own fractions using fun interactive objects. Match shapes and numbers to earn stars in the fractions games. Challenge yourself on any level you like. Try to collect lots of stars!

STUDENT ACTIVITY -- 5th -- NC/TXThis is a distance-learning lesson students can complete at home.The student will use their knowledge of operations (addition and subtraction) of fractions with unequal denominators to solve real world problems.This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.

The Fraction module is separated into five pages.  Each page except the first page has videos and lecture notes. At the end of the entire module are review problems. The review problems are a set of exercises in Derivita that correspond to the skills covered in the lecture pages and the videos.The instructors can choose to assign the practice problems based on their students' needs.This work was created by Kathryn Kozak, and it is licensed under a Creative Commons Attribution 4.0 International License.CC-BY

Students will be able to describe the shares using the words halves and fourths. They'll be able to describe the whole as two of, or four of the shares.
