Pattern Blocks Chapter 3 - Geometry

Pattern Blocks Chapter 3 - Geometry

Years of research on how children learn has shown that the use of manipulatives such as pattern blocks is a powerful tool for developing conceptual understanding of mathematics.Students enjoy working with pattern blocks when they have been allowed time for free explorations. What seems like play to adults is an important part of building confidence and motivation in children.Using Root 7’s Pattern Block resources enables students to be:• Actively involved in doing math, which motivates them and builds confidence. • Provided with excellent opportunities to work together, discuss mathematical ideas, and verbalize their thinking.• Given concrete representations of mathematical ideas, thus providing a visual model to refer to.• Provided with Extra Practice questions to extend and reinforce their knowledge and understanding.How to use• Assign one or more Activity questions to each student and allow them to work individually, in pairs or in groups• Observe the students as they work and ask questions, or ask them to explain their work, to ensure they understand the mathematics• Ensure they record their work as this helps them clarify their thinking and reinforce their understanding.• The More Practice questions are important as they are designed to make the connection from “Hands-on” to “paper and pencil” ie from the concrete to the more abstract symbolic representation.The activities in Chapter 3: Geometry helps students increase their knowledge and understanding of various concepts of Geometry including, properties of shapes, congruence, similarity, and symmetry.Each unit includes Teacher Notes and Answers.

3rd Grade Standard 3.G.2 Real World Geometry TEST PREP MASTERYCheck out these varied learning opportunities!1. Your kids will love the real-world photos that will grab their attention and generate discussion about geometry in the real world. Connect to your document camera or smart board and you’re ready to go.2. Use the 48 standards-based task cards to engage students in relevant practice. (Idea: Put them in plastic protectors and use dry-erase markers.)3. Use the 48 questions in assessment format to measure evidence of learning.Designed for “brain friendly” classrooms, this product covers: 3.G.2 Reason with shapes and their attributes. Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.Order 3rd Grade Test Prep 3.G.2 Real World Geometry TEST PREP MASTERY for your classroom today!

SIMILAR SHAPES : Length, Area, Volume Ratios

SIMILAR SHAPES : Length, Area, Volume Ratios

These 5 worksheets help to explain the effects of enlargement on the area and volume of a shape by looking at the length, area and volume ratios. This is an important topic that is often found difficult by many students.There are three basic worksheets introducing the idea then two pages of harder word problems for extension work. The first worksheet lets students calculate the surface area and volume of simple 1cm and 2cm cubes so they can create the ratios themselves and see how the area and volume ratios derive from the length ratio. Sheets 2 and 3 require students to use the relationships between the ratios to calculate missing areas and volumes.The two word problem sheets are similar to GCSE 9-1 exam questions.For more resources like this please visit the SKILLSHEETS Shop

Symmetry - Differentiated Patterns

Symmetry - Differentiated Patterns

I used these worksheets in Year 4 and the children moved through them at their own pace during the lesson starting with the first sheet. The third activity is quite difficult (two examples in the picture) so even the most able might need to start with the second sheet first. The last sheet is just blank for the children to fill in for each other in pairs if they've blasted through the other three!Thanks for looking!
