This week we will be recapping adding two single digit numbers together to find the total. We will be remembering the skills we need to count on.
-To begin to count beyond 10.
-To add two single-digit numbers.
This week we are recapping adding two single digit numbers together to find the total.
When we are adding we need to remember to not count of all the objects together but we need to count on from the biggest number. We keep the biggest number in our heads and count on. Model using loose parts to keep the biggest number in our heads and count on.
Today we are going to talk about combining two groups of objects to find the total. When we add something the number gets bigger. Remember we always keep the biggest number in our heads and count on. We can use a number line for this to help us.
Model having 6 corks and 4 pebbles. If Miss Gray adds them together how many are there in total? Model ‘I keep the biggest number in my head which is 6.’ Begin counting on from 6, 7,8,9,10. Model using the number line to count on from 6. The answer is 10! Model writing the number sentence. If Miss Gray has 5 pebbles and 3 corks, how many are there altogether? 5+3=8.
Use the counting on from 20 power point to model counting on using pictorial and number lines. The use of the number line is to help us count on so we don’t we forget the number. Model using the number line for other examples with the class. Provide chn with number lines in small groups and some pictorial sums, can they work out the answer?
Provide chn with number lines in learning circles, Give each group a word problem. Can they work out the answer> I.e.: There are 5 chn in the park and 2 more come to play, how many are there altogether? Remind about having the p=biggest number in their heads and counting on using the number line for support.
