Open Up Resources 40 min(s)Support for English Language Learners

Let's look at tiling patterns and think about area. Learning targets: students can explain the meaning of area. Students start the first lesson of the school year by recalling what they know about area (note that students studied the areas of rectangles with whole-number side lengths in grade 3 and with fractional side lengths in grade 5). At the end of this lesson, students are asked to write their best definition of area.
