Mathematics for schoolchildren aged 7-9 is not only counting, but also various geometric tasks. Repeating a pattern according to a sample, assembling from a construction set according to a scheme - this is also mathematics. The sequence of work with any new geometric material is as follows:
- First, free play to get acquainted with the details, “think up whatever you want, assemble your own picture”;
- "Assemble according to the pattern from 2-3 pieces" (in this mosaic the angles are not right, so even a candy made of three pieces cannot always be easily repeated by children);
- "Assemble according to the large color scheme by superimposing" (we put the parts on top of the drawing);
- "Assemble according to the large black and white diagram and paint each piece in the desired colors";
- "Assemble according to the reduced color scheme";
- "Assemble according to the reduced black and white scheme and paint each part in the required colors";
- "Come up with your own picture and circle it";
- "Come up with your own picture and draw it using the triangular cells."
We are used to working with cubes, bricks and other figures that have right angles. Mosaic in this regard is much more complex and interesting, because the parts have angles of 30, 60, 120 and 150 degrees.
In this notebook, in addition to small plot pictures, we have collected many different tasks on symmetry. To work with these tasks, you may need a rectangular pocket mirror. You can use a mobile phone screen as a mirror.
Symmetry is a rather complex topic, and at the same time very beautiful. We explain symmetry to children as a pattern on the wings of a butterfly: the left wing of a butterfly has almost the same pattern as the right wing, but symmetrical, reflected, like in a mirror.
We suggest assembling butterflies from mosaics to feel the beauty of symmetry. Patterns can have one, two, three and even six axes of symmetry. With one axis of symmetry you get a butterfly, and with six axes - a snowflake or a kaleidoscope pattern.
This workbook contains several simple mosaic tasks about fractions: if a hexagon is a whole, then a red trapezoid is a half, a blue rhombus is a third, and a triangle is a sixth.
You can create a variety of ornaments and beads with mosaic pieces. The simplest patterns are easy to continue: trapezoid - rhombus - trapezoid - rhombus... But we offer you a collection of more complex patterns. You can continue the ornament beyond the task sheet!
A triangle is a very simple figure, and even preschoolers know what this figure looks like. But can you assemble one triangle from three trapezoids? And how to assemble a triangle if you are given a hexagon, a triangle and three trapezoids? We have made a collection of puzzles of this type about triangles, rhombuses, trapezoids and hexagons.
Even adults cannot always solve such problems quickly.
Remember that the child's leading activity is play, and many children often lack free time for mathematical creativity. Our tasks are for joy and creativity.
