Geometry Apps 

 

 

 

App Name: Geometry 4 Kids

Cost: $.99

Device(s): Android, iPad, and Kindle Fire

Appropriate Grade(s): K – 5th

Content: Geometry

Common Core State Standards:

CCSS.MATH.CONTENT.K.G.A.1 - Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.

CCSS.MATH.CONTENT.K.G.A.2 - Correctly name shapes regardless of their orientations or overall size.

CCSS.MATH.CONTENT.1.G.A.1 - Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

CCSS.MATH.CONTENT.2.G.A.1 - Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.1 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

CCSS.MATH.CONTENT.2.G.A.2 - Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

CCSS.MATH.CONTENT.3.G.A.1 - 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.

CCSS.MATH.CONTENT.3.G.A.2 - Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.

MACC.4.G.1.1- Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

MACC.4.G.1.2 - Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

MACC.4.G.1.3 - Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

MACC.5.G.2.3 - Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

 

Description: Geometry for Kids allows all elementary students the opportunity to practice a multitude of geometry concepts. This app doesn’t just throw students out there to figure out the concepts alone, but provides them with a verbal lesson of the skill and then gives them the opportunity to practice. The problems in which students encounter, are real-life situations that will help students to take more meaning from what they are learning. Most importantly students are challenged to think critically and given the freedom to work at their own pace.

 

 

 

 

App Name: Geoboard

Cost: Free

Device(s): iPad, iPhone, and the Web

Appropriate Grade: 1st -5th

Content: Geometry

Common Core State Standards:

CCSS.MATH.CONTENT.1.G.A.2 - Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

CCSS.MATH.CONTENT.4.G.A.2 - Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

 

Description: Geoboard is a virtual manipulative app that allows students to explore the world of geometry. Students are able to manipulate colored stretch bands to form line segments and polygons. Through this app, students gain great practice with concepts such as angles, area, fractions, and perimeter.
