Hola a todos,

Please sign in as usual.
Here is a description in case you have difficulty.
Uno mas y uno menos (one more and one less).
Pretend you are playing a piano and use your fingers to count the math way. Left pinky is one, index 2 and o on.
Parents show students fingers from one to 5 and ask cuanto es uno mas… How many is one more?
Parents show students fingers from 5 to 1 and ask cuanto es uno menos? How many is one less?
Please ask students how they know? Como lo sabes?
Targetet answer is… because if you take away 1 less or one more from # the answer is #. It is ok if they use their fingers to count however we are trying to build automaticity thus encourage them to try it without counting if they can.
Variation… 2 mas, 2 menos etc.
Challenge: Try finding one more and one less with numbers up to 20? Use a number line. Here is a video for the challenge…
Post videos on class dojo under your portfolio of this activity. Can’t wait to see you practicing uno mas y uno menos.
