Problem-based Digital Making Tasks Make a device that would display a student’s piggy bank balance after each deposit. Compare two offers: The first offer is that the teacher gives her $3 today and $222 everyday thereafter. The second offer is to give her $3 today; then each subsequent weekend (Saturday and Sunday), he gives her double the … Continue reading Bank Deposit Computer

# Prime and Composite Number Detector

Problem-based Digital Making Tasks Is 7081 a prime or composite number? Make a prime or composite detector. How CT may Support Mathematics Learning The use of conditionals and Boolean operators will come into play when checking whether a number is prime or composite. In particular, students will need to loop a function to check the divisibility of a … Continue reading Prime and Composite Number Detector

# Fibonacci Sequence Machine

Problem-based Digital Making Tasks To generate terms of Fibonacci Sequence and observe its parity. How CT may Support Mathematics Learning Recursive repetition will support the generation of terms in the Fibonacci Sequence. Problem solving will be encountered with the first two entries of the Fibonacci Sequence being 1 and 1. Naming of two variables will … Continue reading Fibonacci Sequence Machine

# Lesson on 3D Trigonometry with 3D Printing Pens

A series of lessons were designed to help Secondary 3-4 students visualize the angles formed (i) between lines, (ii) between a line and a plane, and (iii) between planes, which were found to be difficult to learn among secondary mathematics learners. These lessons incorporated both 3D printed models by a 3D printer, as well as … Continue reading Lesson on 3D Trigonometry with 3D Printing Pens

# Lesson on Properties of Prisms and Pyramids with 3D Printing Pens

The two lessons described here were of Primary 5 and 6 levels, where the first lesson focused on the properties (shape and number of faces, including lateral faces and bases) of different forms of prisms, and the second lesson focused on those of the pyramids. Students spent most of class time using 3D Printing Pens to … Continue reading Lesson on Properties of Prisms and Pyramids with 3D Printing Pens

# Lesson on Euler Formula with 3D Printing Pens

Active learning, hands-on Making, inductive reasoning, and making generalisation about the Euler Formula (V+F-E=2) using the 3D Printing Pens (see figures below)

# Calculus Lessons with 3D Printing Pens

In these lessons, we explored the affordances of drawing functions in the Cartesian plane with 3D pens in a high school calculus classroom. During the lesson, students were to draw the graphs of basic functions, such as y=x^2, as well as a “line” in 3D. Although the task is 2D in nature, in that students … Continue reading Calculus Lessons with 3D Printing Pens

# Lesson on Volume of Prisms with 3D CAD

A teaching experiment involving three and a half days of 75-minute lessons was conducted for consolidating student learning of the volume of composite solids. The teaching experiment took the form of an open-ended class project, which objective was to, “Design a keychain and have it printed in 3D; consider the time and cost of printing … Continue reading Lesson on Volume of Prisms with 3D CAD

# Lesson on Volume of Oblique Prisms with 3D Printing Pens

This Secondary 1 lesson is an extension of volume of prisms from Primary grades. In this teaching experiment, we focus on students' common misconception of thinking slant sides as the height of the prism. Our objective was to design a group activity with 3D Printing Pens which foster discussion to help students visualise the relationship … Continue reading Lesson on Volume of Oblique Prisms with 3D Printing Pens
