This week we played addition games and continued writing addition sentences to 20. We looked at strategies and ways of adding more than 2 numbers to make 10 and 20. We are exploring the relationship between addition and subtraction and enjoyed playing a game with number cards.We added 2 cards and used these numbers and their sum to construct subtraction sentences. We explored the number chart to 100 and looked at the concepts less/more, greater than. We counted on in 3's, counted backwards from any number to 100 and reviewed counted by 5's and 10's from any given number.
