Math lesson #5
This time we continued Autumn topics, and worked with numbers using paper ladybugs, improving number and quanity skills and numeric intuition. Five-year-olds had to add some dots on the ladybugs' backs to the total of 5. For seven-year-olds, they had to add enough dots to get 10.
For the 5-year-olds:
Writing out the ways to get 5 and 10 as a sum of two numbers:
Everyone took a ladybug with 5 dots and "flew" it around the room. I count from one to five, or backwards from 10 to 5, and after the word "five," start catching those who are not in the "house" (on the couch):
Then the same with 10-dotted ladybugs: counting 1..10 and 20..10.
Then it was time to put ladybugs to sleep. Their nests had to have leaves with numbers adding up to the number of dots on a ladybug.
The nests were like these:
Next game: throw two dice. The first die gives the number of tens, the second die - the number of ones..
Use math matrices and usual paper to record those numbers:
Compare and arrange in the increasing order:
