Fractions can be used to understand halves of a unit square.
Area word problems using a real world context pose new mathematical challenges for students to negotiate.
Students write expressions to find the area of compound figures.
Lesson plan in which students calculate area, build areas to a given amount, and calculate the perimeter with the use of Legos. Step by step instructions and videos are provided. CCSS.Math.Content.3.MD.C.7.c Use area models to represent the distributive property in mathematical reasoning.
Students need time to connect area and perimeter. This two day exploration sets the stage for our short unit.
Students build models wherein the area remains the same, while changing perimeters.
Students use their understanding of area to have a meaningful debate about a building plan.
Dividing an irregular shape into rectangles helps students find the area of an irregular shape.
Students take their knowledge about area of rectangles, squares and triangles and apply it to parallelograms, trapezoids, and composite shapes.
Students look for break apart irregular polygons to make arrays to find the area of these common shapes.
Students apply what they know about area of other polygons to develop a formula for finding the area of a triangle.
Creating rooms with different dimensions but the same area improves understanding of multiplicative principles.
Students develop a meaning of multiplication through the use of arrays.
Today's lesson is all about asking and answering questions so we can strengthen comprehension.
A lesson plan with all resources included for asking and answering questions to strengthen comprehension.
Knowledge in Action! Today you will find out if the students are understanding the idea of decomposing and composing shapes with pattern blocks.
1, 2, 3,... Students will demonstrate their counting ability as they count sets of objects between 40-60.
Today you will get an opportunity to conduct an assessment interview that will look at how well your students are measuring with inch tiles.
This is an introductory lesson on the concept of theme. Students choose two words that sum up the theme of the novel "So B. It" by Sarah Weeks. They then analyze a passage to find evidence of their choices and create a theme map. They follow this up by applying the strategy to their own independent reading.
SWBAT use strategies to identify rational numbers on a number line.
