FREE for a limited time – Area of Figures, an excellent educational app for teaching area from Brainingcamp LLC.The app helps kids understand how to find the area of 4 different figures:  rectangles, parallelograms, triangles, and circles. For each figure there is a narrated lesson (with visual models), virtual manipulatives for kids to explore, practice questions to check understanding, and a challenging game for additional practice.

What a GREAT app! The lessons are wonderful – clearly explained and involve students along the way. The manipulatives are designed to promote understanding of the concepts presented. The practice questions give students and their teachers a check of their understanding. And, the challenging games helps kids further master the topic. It would be a fabulous for grades 3 and beyond!

Common Core State Standards met:

• 3.NF.1. Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
• 3.NF.3 – Explain equivalence of fractions and compare fractions by reasoning about their size. Understand two fractions as equivalent (equal) if they are the same size. Recognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3).
• 4.NF.3 – a. Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
• 5.NF.3 – Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b).
