Checkpoint 1

This is the first level of digital castle setting. What numbers are there on the map? Can you find any regularity in the numbers in the grid? Are there any other rules?

The main purpose of the first level is to let children boldly describe the rules in the digital grid through observation, encourage children to discuss openly and find out more rules (for example, each row and column has the number 1~0; There are 1 numbers from left to right horizontally and 1 numbers from top to bottom vertically; The last digit of each column is the same and so on. )

secondary

The second level of digital castle is "drawing numbers according to instructions".

a.？ Find the number 1~ 10 and draw a line by the number 1~ 10.

B. Start with the number 0, five numbers of five, and circle the counted numbers with a pen.

c.？ Circle two numbers that start with 3.

D. Circle the number 10. Find a number less than 10 and draw a √ on a number greater than 10.

third stage

Level 3 needs to find out the missing numbers in the digital grid and supplement them completely!

Fully Good

Band 4 also needs to find out the missing numbers in the number box and supplement them completely, but the difficulty is greatly improved ~ come and challenge!

The main goal of Level 4 is to train children to find the pattern of number arrangement on the digital grid, so as to improve their perception experience of the number sequence within 100.

Family activities

At home, parents can play "lost number" with their children. Mom and dad count slowly from any number, skip a number in the process of counting, and let the children judge for themselves which number is missing. For example, 1, 2, 4, 5, 6 or 7, 6, 4, 3, 2.

If children have difficulty in answering numbers, parents can also say: 1, 2, empty, 4, 5, 6 or 7, 6, empty, 4, 3, 2.

Parents can also say a string of numbers and change the order of two of them, so that children can judge which two numbers have changed, such as 24, 25, 27, 26, 28 and 29.
