More About Our Mental Math Strategies...

  

We are learning more addition and subtraction mental math strategies!! We have now learned 6 different strategies. A collection of these are coming home the beginning next week to update from the ones sent home last month, as well as posted below. Please use these at home to help with our math work that comes home and to practice these strategies when you get a chance to build our skills of our math facts! Students are loving the math challenges that are presented and should be proud of all they are learning! 

This week, we have worked on a new subtraction strategy called 'Wipe Out'. This is for all other subtracting questions where the minuend and the subtrahend are the same number, we will always have a difference of zero! We will be focusing on this throughout this week and reviewing all strategies on Thursday. Friday we will have our 5 question quiz to see how we are doing.  

Following the learning of our 6th mental math strategy, and as marked on our mental math strategies poster, we will spend some time learning more about general math strategies of Count On for all addition sentences and Count Back for all subtraction sentences. These will help solidify the concepts of addition and subtraction. As well this will open our learning about learning how to add and subtract with bigger numbers. While that won't be mental math, it will be the next step in understanding numbers, and ways we can use hands on materials or drawings to help work with larger numbers.
