Today and the last couple of days I learned decimals with the hexagons group. .We use the deci-pipes. I don't know lots of decimals but it is so cool to learn something new.I would like to learn how to add and subtract decimals because you need to know that so that you can add up money. This photo shows how I made`2.45 on the deci- pipes. That mean 2 wholes, 4 tenths and 5 hundredths.
