Because counting to 20 is so difficult?
Via EAG News:
How are parents supposed to help their children with Common Core math when it’s just flat-out wrong?
Parent Mina Boyd’s kindergartener was given an assignment to count the number of apples on the page and write the number. The worksheet is titled “Count and Write 20,” so presumably, there would be 20 apples to count.
Except there’s 19.
“They ask her to count and write 20. So she counts…counts again and again. And says mom, ‘there’s only 19,’” Boyd wrote on the Parents and Educators Against Common Core Standards Facebook page.
