This book offers yet another opportunity for adults and children to engage in fun and useful activities. Together, you can open the door into the fun world of geometry. Solving one problem at a time, your child will: Get to know various figures assembled using equal triangles, equal squares and other equal shapes; Get to know the problem of covering parts of a plane; Create various shapes and get to know their properties; Practice perception and preciseness; Develop motor skills; Practice persistence and working independently; Develop research skills and creativity; Successfully prepare to start school. You will read out the instructions to your child and encourage them to complete the tasks independently. You will explain to them how to organise the figures when covering and assembling the shapes in question. Filling a shape with other shapes requires assembling the shapes so there are no empty spaces in the object that’s being filled. Also, the shapes should not cover each other or go outside the lines of the shape in question. Even though this book was intended for children aged 5 to 7, you should keep in mind that developmental characteristics vary among children, so you shouldn’t be discouraged if some tasks prove to be too difficult for your child. Do not insist on solving them – you will see how exciting it will be when your child is more successful at a later attempt.
At the end of the book, you will find enclosed the shapes needed to solve the problems. They can also be used to create new shapes. However, they can easily get misplaced or mixed up. This is why we suggest taking them out and placing them in separate envelopes. You can mark the envelopes by drawing or sticking the matching shape on it. For example: Purple triangles

Fill the following shapes with triangles. How many triangles do you need for each shape?
Assembling various shapes using blue triangles Try to complete the following tasks quickly: Assemble a square using two triangles. Assemble a triangle using two triangles. Assemble a square using four triangles. Assemble a triangle using four triangles Assemble a square using eight triangles. Assemble a triangle using nine triangles. This grid can help you assemble the shapes.
Using blue triangles enclosed in this book, assemble the shapes following the models shown in this picture. Use five triangles for the first figure, four triangles for the second one, ten triangles each for the third and the fourth one, and twelve for the fifth and the sixth one.
Which of these shapes can you assemble using eight triangles? 15
Multi-coloured triangles Using four triangles like these, assemble the figures as shown in the picture.

Using the shapes enclosed in this book, assemble the figures as shown in the picture.
Shapes made with three squares We will get to know shapes assembled using three equal squares that are connected with their edges. Using three, four, five or more squares, you can make various shapes. Using at three squares, we can only make two shapes. You will find models of these shapes the end of the book. Each shape is placed in the square grid by aligning the edges of the shape with the lines in the grid. The shape can assume various positions. grid. For example: the first shape can take two different positions within the square
How many different positions can the other three-square shape have in the square grid? Draw them.

Books from the Fun World of Geometry edition are designed to develop mathematical skills, independence and persistence in children, but also teach them how to be precise and notice patterns. These books will improve their confidence in problem solving and help them successfully prepare to start school.
