Has the terminology for naming a group of ten as "one ten" changed to "10 ones" formally? Are we supposed to tell students to talk about numbers greater than ten as "10 ones and ___ ones" vs. (example) 1 ten and 3 ones for 13?
This might seem silly, but I wonder if someone could clarify... I teach kindergarten and we are in the process of translating some lessons from different sources including Engage NY lessons and many documents or samples we've looked at say (example) "write the missing number ... I have 10 ones and ___ ones." to describe number 11 or any other number with a ten and extra ones... some even ask it as "write the following number "ten four"... how does that even make sense!? maybe if it said, write the number that represents one group of 10 and four or 1 ten and four or 10 and four more.... help!
I teach in a Spanish Dual Immersion program and it's particularly confusing in Spanish - Are we not identifying a group of 10 ones as a "ten"/decena anymore? (10 ones and ___ ones/10 unidades y _____ unidades)???
