  • Instructions

    Create your course assignments by selecting questions from our bank of end-of-section exercises, as well as enhanced interactive examples with videos.

    While doing their homework, students can link to the relevant interactive examples from the book and work through them again and again for additional practice before answering the question.

    Students can view and hear additional instruction through the 2-5 minute Watch It links. Students will also find helpful links to online excerpts from their textbook, tutorials, and videos.

    Read It - relevant textbook pages

    Watch It - videos of worked examples

    In this assignment we present several textbook questions from Mathematics for Elementary School Teachers 1/e by Ricardo Fierro published by Brooks/Cole. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.

For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer.
