Mathematics - One More and One Less


Today in our Maths lesson we will be exploring one more and one less. 


First - We would like you to explore the One More and One Less PowerPoint. 


Then - We would like you to have a go at the one more and one less challenges. We would like you to demonstrate your findings on a separate piece of paper by drawing dots or lines to represent your counting.


For example one less than 8 is 7 and one more than 8 is 9.

smileysmileysmileysmileysmileysmileysmileysmiley = 8

smileysmileysmileysmileysmileysmileysmiley = 7 (1 less)


smileysmileysmileysmileysmileysmileysmileysmiley = 8

smileysmileysmileysmileysmileysmileysmileysmileysmiley = 9 (1 more)

 You can use a number line to support you.
