The learning tools that need to be prepared for the second grade are: division exercise table within the table, ten thousand-meter table, simple balance and so on.

1, table division exercise table: see page 4 of volume 2 of the second grade school card of People's Education Press. This is a learning tool to help students practice division in the table. Write the dividend of all divisions in the table from left to right in turn. Before doing exercises, you can prepare 9 small number cards and write these 9 numbers 1~9 respectively.

When doing the problem, take a digital card, put it behind the corresponding vertical line and say the quotient of division from top to bottom in turn. For example, take out a digital card with "2" written on it and put it behind the second vertical line. It is good to calculate 4+2, 6+2 and 8+2 ........................................................................................................................ in turn.

In order to connect horizontal lines and vertical lines, for example, to calculate the division of 6, you can use the sixth horizontal line first, and then calculate 42+6, 48+6, 54+6 according to the vertical line. Or one student can point to a number above, and another student can quickly tell the quotient obtained by dividing it by a number. You can also compete with two people.

2. Table of numbers within 10,000: See page 19 of the second-grade study card printed by People's Education Publishing House. Teach reading and writing of numbers within 10 thousand. The usage is basically the same as the number table in the second volume of senior one. Please refer to Page 10 of the Teacher's Teaching Manual, Volume II of Senior One. ?

3. Simple scales: When teaching the understanding of kilograms, schools without scales can make simple scales. The manufacturing method is: use two pieces of wood, one as a beam and the other as an upright post. Nail a small nail in the middle of the beam as a pointer, and the small nail is perpendicular to the beam. Draw a thick line along the center of the column.

Nail the midpoint of the beam to the upper end of the column, but don't nail it, so that the beam can rotate around the midpoint. Then hang small boards of the same size at two points with equal distance from the midpoint at both ends of the beam, so that the small nails coincide with the vertical line, and then fix the small boards on the beam.

Math learning toolbox

1 grade, grade one and grade two mathematics will involve some preliminary understanding of mathematical concepts such as counting, time and geometry. Due to the weak abstract ability of junior students, learning tools are often needed in teaching, such as sticks, calculators, clocks and watches, jigsaw puzzles and so on.

2, the second grade study length units, but for children, meters and centimeters are more abstract concepts, so if children can measure things at home with a ruler and meter ruler, I believe children can have a clearer understanding of meters and centimeters.

3, children should be able to judge right angles, there is a right angle on the triangle can be used to judge, you can draw a right angle with the right angle on the triangle.
