Addition of points within 3: the maximum value of addition is 6
Addition of points within 4: the maximum value of addition is 8
Context requirements:
When children complete “21 questions for addition within 5 and 21 questions for subtraction within 5”, there are two characteristics:
1. 50% of the children can count by mouth, the other 50% of the children who can’t do it draw circles, but they are more accustomed to counting with their fingers.
2. Young children do not understand the meaning of plus and minus signs, and subtraction problems are also made into addition problems.
The above shows that the level of children in the middle class should be in the stage of “points in kind”, so I hope to turn the numbers of addition questions into graphics, so that children can directly count and write numbers. At the same time, in the learning tools of food exchange cards 1.0, each child can write the corresponding number according to the number of food pictures, which proves that the child’s accurate rate of points is very high.
Therefore, the purpose of this set of learning aids is to let children understand the meaning of “+” and “-“: increase and decrease, (there are physical pictures, temporarily exclude the interference of the number 0 option)
Material preparation:
1. PNG image
2. WORD template (horizontal version)
Code execution
Originally, I only wanted to use “fruit pictures”, but later I found that there were too few fruits, and there would be repetitions when randomized, so 23 kinds of food were used together

Generate result:
Within 3: the maximum value of addition is 6
Within 4: the maximum value of addition is 8
Within 5: the maximum value of addition is 10
Within 10: the maximum value of addition is 20
Within 15: the maximum value of addition is 30
Less than 20: the total maximum number is 40
Insights:
Print different numbers of cards in batches to increase the difficulty and let children perceive the usage of “plus sign”.

Crop swap card
Analysis:
1. Children choose learning tools with difficulty coefficients of 1, 2, and 3 according to their own level (within 6, within 10, and within 30). Number 23 chose the 2 hardest papers. Children count points and write out the total, all of which are correct.
2. After the children cut the cards, the exchange behavior is less, and it is not good enough. They are more likely to play games such as jigsaw puzzles and collecting coins with the cut out pictures.
3. The patterns on the cards are small, and children cannot color them.
4. Children explore other ways to play with the note. (lots, tabs, circles, etc.)
Description:
The number of additions in this code is to draw random numbers (random.choice), which can only ensure that the total number C of A + B does not exceed a certain number, so there may be adjacent questions in the title that are consistent (5 bananas + 1 banana, 5 burgers + 1 burger),
Therefore, it is not suitable for subtraction (the number of A must be greater than B (regardless of 0).
