common core for 1st grade tens/ones is GARBAGE. I'm having to take my kids out and go over basics because they don't understand the concept of what makes a ten much less how many tens are in 57.
We're using cuisenaire rods (tens rods, ones units). I have a laminated work mat that shows a tchart with tens and ones written at top. they build their number with manipulatives then write it with the dry erase marker.
the hardest part is that the ones is on the right and not the left (opposite of reading which is left to right)
then, the "teens" place are said funny unlike the 20s90s where the tens number is said first. Unlike 13 (thirteen) where the ones place is said first.
SO CONFUSING for the babies.
