Teach Fractions & Transformations with SmartBoard Mini-Movies

Fractions

There are 15 new SMARTBoard mini-movies that will help elementary teachers introduce their students to fractions. The animations show pies and bars divided into halves, thirds, fourths, fifths, sixths, and eighths. Click the buttons below each model to see the fractional parts of each model become shaded. Teachers can use them to teach the following objectives:

• Describe what a fraction represents and what a numerator and denominator are.
• Convert fractions between symbol and picture representations.

Included in the 15 are four mini-movies that teach equivalent fractions. These show equivalent fractions for thirds and fourths.

Transformations

The most popular page on misterteacher.com is the transformations page on Alphabet Geometry. This month I've created a new set of advanced transformations mini-movies for older students. These animations show letters transforming on a coordinate plane. Your students will be able to watch letters rotate by four different angles: 90º, 180º, 270º, and 360º. There is also an advanced transformations student activity. You can use these mini-movies and the student activity to teach the following objective:

• Predict and describe positions and orientations of two-dimensional shapes after transformations such as reflections, rotations, and translations.
