As a former elementary school teacher and now a legal/business writer specializing in educational resources, I’ve seen firsthand the power of hands-on learning. Introducing geometric concepts early, especially with engaging tools like pattern blocks, can lay a strong foundation for future math success. This article explores the benefits of using pattern blocks, delves into common activities like "the greedy triangle," and provides a free, downloadable template to help you solidify your students' (or children's!) understanding of shapes. We'll cover everything from pattern block shapes names to identifying kindergarten triangle shaped objects and even exploring the name the lengths of the sides of three rectangles. Let's build some geometric intuition!
Pattern blocks – those colorful, geometric pieces – are more than just fun to play with. They're a powerful tool for developing spatial reasoning, problem-solving skills, and a deep understanding of geometric properties. They allow children to manipulate shapes, explore relationships between them, and visualize fractions and symmetry. Unlike abstract textbook definitions, pattern blocks offer a tangible, concrete experience.
Before diving into activities, let's ensure we're all on the same page regarding the shapes themselves. Here's a breakdown of the standard pattern block set:
“The Greedy Triangle” is a classic pattern block activity that beautifully illustrates the concept of area. The premise is simple: a triangle wants to become a square. It "eats" other shapes to achieve this goal. This activity encourages children to experiment, observe, and deduce relationships between the areas of different shapes.
How to Play:
This activity naturally leads to discussions about equivalent area and the relationship between different shapes. It’s a fantastic way to introduce the idea that different shapes can cover the same amount of space.
This is a great quick assessment or discussion starter. The answer, of course, is two equilateral triangles. However, the value lies in the reasoning process. Encourage students to explain why two triangles cover half the rhombus. This reinforces their understanding of fractions and geometric relationships.
Connecting geometric concepts to real-world objects is crucial for young learners. Ask students to identify kindergarten triangle shaped objects around the classroom or at home. Examples include:
This exercise helps them see that geometry isn't just an abstract concept; it's present in the world around them.
Moving beyond triangles, let's focus on rectangles. Understanding the lengths of the sides of rectangles is a fundamental skill. Here's a simple activity:
Provide students with three different rectangles (drawn on paper or using pattern blocks). Ask them to:
This activity reinforces the vocabulary of length and width and introduces the concept of perimeter.
To support your teaching or homeschooling efforts, I've created a free, downloadable template. This template includes:

Once students have a solid grasp of the basics, you can introduce more challenging activities:
Here are some helpful resources for further exploration:
| Shape | Number of Sides | Equal Sides? | Right Angles? |
|---|---|---|---|
| Triangle | 3 | Yes (Equilateral) | No |
| Rhombus | 4 | Yes | No (unless it's a square) |
| Trapezoid | 4 | No | No |
| Hexagon | 6 | No | No |
| Square | 4 | Yes | Yes |
Pattern blocks are a versatile and engaging tool for teaching geometric concepts. By incorporating activities like "the greedy triangle" and focusing on real-world applications, you can help students develop a strong foundation in geometry. Remember to encourage exploration, experimentation, and critical thinking. The free template provided will serve as a valuable resource in your teaching journey. Happy learning!
