For younger kids, teachers can use this engaging game to reinforce spatial-relations skills. The geometric shapes, ABCs, faces, and star bursts will keep kids playing. The system keeps track of multiple players; make sure to set them up before they start so they can save their solutions.Continue reading Show less
Doodle Fit is an engaging geometric puzzle app with cool features and awesome flexibility. Kids can choose sketchpad or chalkboard graphics schemes. Gameplay requires them to fit mostly four-unit geometric shapes, with a few one- and two-unit shapes thrown in, into another shape without empty spaces or overlaps -- pretty basic puzzling. Kids drag and drop shapes to place them, tap or drag off to remove, and get hints when they're stuck. Blocks don't rotate, which limits possibilities but probably makes solutions easier since there are fewer options. Kids can skip a level and return to it later.
With 110 levels and multiple solutions for many of the puzzles, Doodle Fit will keep kids solving problems for quite a while. Each puzzle challenges them to study the whole to see where blocks can and can't fit. Early puzzles are quite approachable for second and third graders, but difficulty ramps up quickly.
The app tracks total time and number of moves used to solve each puzzle. It's simple and streamlined, although it does connect to Facebook and has some in-app purchase options. Players can share high scores via the Game Center social network, but participation is optional.
Key Standards Supported
Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
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.
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.
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
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.
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.
