Numerical rods with numerals

Introduction to the world of numbers from 0 to 10. Numerical bars with plates of numbers

Material:10 rods, the size of the corresponding red bars. They differ only those that are divided on red and blue intervals with a length of 10 see The shortest rod is red. Wooden plates with written on them numbers from 1 to 10.

Direct goal: to see the numbers 1-10. To see the relationship between quantities and symbols.

Indirect aim: to familiarize with the metric system.

Age: about four years. How to work with the material. All rod lie in a mess on the carpet. The child arranges the rods in that same order which was studied on red bars. Binding to well friend. The teacher takes the first 3 rods and separates them from the rest. It puts the shortest bar before the child, concerns it and speaks: The "times". The first step of a lesson about names. He puts a second rod in front of the child, concerns in turn both it pieces and said: "one, two.- Two!" Similarly, he enters with the third rod. Every time start counting from the first touch and then turn the next segments of rods, the child memorized a series of sequential numbers. Need to count the segments, not the rod. The teacher mixes bars and say: "Give me the rod 2!", or: "Give me 3!" Every time he ask the child to count. The second step of a lesson about names. Teacher takes one of three bars, offers the child to count its pieces and to say what this rod. The third step of a lesson about names. If the child interested, the teacher can enter and other bars. When the exercise is finished, the teacher asks the child again the broken order of bars. In the following exercises you again and again to call rod. It is very important that at the end of exercise the child again saw material as a unit.

Control over mistakes is carried out by the teacher.

Further exercises:

• from moved the rod to choose one and count its segments. Re verification should be carried out not only by comparison of lengths, but with using numbers; ― "please Give me next/previous post!";
• to count only red or blue segments of the rod;
• call number, starting from the largest to the smallest;
• to complement the rod to 10 (9-8-7).

Preparation for addition:

• after you have entered the figures from rough paper, it is necessary to use numerical plates;
• rods are in the correct order on a carpet. The child orders numerical plates, having them near corresponding bars;
• numerical plates lie in a row in the order rod ― randomly. The child picks up each rod to the corresponding plate;
• the child arranges the rods in the room. He takes any sign and looking for the appropriate rod;
• rod handed out to children. Children with barbells quickly form a number 1-10. Rod change and build a new series.

The following exercises are group games:

• Rod 6 comes to me! Now, again, quickly form the correct number!" All the children are equal to the rod 6;
• rod or numeric signs are distributed among the children. "Seek his (lesser or greater) neighbor!";
• we go and believe at the same time, then go back and counting OK but slow! The bill is up to that number, which is represented a barbell or figure in child hands;
• when walking to allocate even or odd numbers, saying them louder or stronger walking legs.

Application.To hold games in which children could apply their acquired knowledge about numbers, for example, the following game. On the expansion cards are worth the number 1-10. Handing out cards to children. Each child is asked to bring so many subjects, what number is specified in its card, and put these items on the carpet.
