For young children, the addition and subtraction of mathematics is simply as difficult as the sky. Parents counseling, while children can not.
recruited children around to learn addition and subtraction. There are probably three unclear questions from parents:
has taught countless times, why is addition and subtraction still unclear?
has just finished the wrong question, why did you turn your head and do it again?
has clearly learned addition and subtraction, why do not know how to use addition and subtraction when starting word problems?
Many people may think that it is possible to learn something so difficult to learn over and over again! In fact, will it be second, the key is whether the child understands.
For children who don’t understand, addition and subtraction is like A+B=C. They don’t understand what it is and they can’t learn it. For children to be able to understand
, language communication alone is not enough. It should also combine novel and interesting ways to help children understand addition and subtraction.
recommends 3 mathematics teaching aids that can be DIY at home to enhance children's mathematics comprehension and easily teach them addition and subtraction.
01
Find a digital partner for the bunny
The purpose of making the bunny teaching aid is to narrow the distance between the child and the boring number through the little animals that children love.
also uses interactive methods to make children interested in numbers, starting from simple numbers to help children understand mathematical addition.
✎Prepare materials
white cardboard, colored pens, scissors, solid glue
✎specific steps
1. Use white cardboard to cut out three large circles, three medium circles, three small circles, and six long Oval shape, six small rectangles.
2. Take out one for each circle and two for the long oval. The small circle represents the tail of the rabbit, the large circle represents the body of the rabbit, the middle circle represents the head of the rabbit, and the oblong represents the ears of the rabbit.
3. Stitch them together, and take out colored pens to draw the eyes, nose, and mouth.
4. After making all three bunnies, parents can write numbers 5-7 on the rabbit's body, and write the addition of these numbers on six small rectangles.
Now that our little rabbit teaching aids are finished, parents can say to their children: "Each little rabbit represents a number. Only if the number is added correctly can the little rabbit find its buddies. Let's help it!"
During the production process, parents can also invite their children to join together, let him find partners for his rabbit friends, they will be more willing!
02
DIY paper plate learning subtraction The function of
paper plate teaching aid is to abandon the boring learning style in the past, and children can easily grasp the relationship between number subtraction and quantity by gently turning the dial.
✎Prepare materials
white cardboard, crayons, scissors, ruler, bamboo sticks, nails
✎ specific steps
1. Cut the white cardboard into large circles, and use a ruler to divide six pieces, starting from the center of the circle. line.
2. Draw different amounts of food or objects in six parts, such as three apples and five pears.
3. Cut off one part on a single circle, and write the corresponding subtraction of numbers on the remaining five parts, such as: 6-3=3, 7-2=5, etc.
4. Use a bamboo stick to pierce the apex at the center of the circle, and use the nail as a pivot to rotate. The
paper plate teaching aid is ready. On the one hand, using the same amount of objects can strengthen children's cognition of quantity, on the other hand, using objects in life is more convenient for children to understand the number and subtraction.
When playing with the child, parents can let the child rotate the paper plate at will, and help the object find the destination according to the above subtraction. Which is the corresponding subtraction?
Children understand the relationship between subtraction and quantity, so they will naturally do word problems.
03
DIY dental addition and subtraction artifact
The purpose of dental addition and subtraction artifact teaching aids is to replace abstract numbers with concrete things to help children understand the meaning of addition and subtraction. Parents can start with numbers within ten and gradually increase the difficulty.
preparation materials
hard paperBoard, crayons, white paper, scissors
Specific steps
1. Draw the dentist and the child with decayed teeth on the cardboard. The child’s teeth are not drawn yet.
2. Then draw the plus and minus fill in the blank box, and cut out ten small triangles of the same size and painted black.
dentist's teaching aids are relatively simple to make, except for drawing, but they are also a synthesis of the first two teaching aids.
When parents invite their children to participate, they should first tell them a number for the child to put dental caries in the mouth of the child. Of course, at this time, they can also tell the child the story of dental caries to reduce the child's tension.
can assume that this child has cured two teeth. At this time, the child needs to take away two teeth. Parents can ask the child how many teeth are left? Finally, ask the child to fill in the box with the number and the addition and subtraction book, and it will be completed if it is correct.
This kind of small game not only allows children to understand addition and subtraction, but also allows them to understand the connection between word problems and games, and will reduce the sense of rejection of word problems.
Therefore, if children have difficulty learning addition and subtraction, parents can try to make the above three small teaching aids so that they can use games to understand numbers, understand addition and subtraction, and improve their sense of number.
If the child understands, it will naturally. Improve your math thinking while learning happily, let your kids try it out!
