00:00:01.807 --> 00:00:05.415
Today we are going to learn about the split and jump strategy
2
00:00:05.543 --> 00:00:07.885
What is the split and jump strategy
3
00:00:08.007 --> 00:00:10.556
First let's start with the split strategy.
4
00:00:10.856 --> 00:00:13.164
Share what you think it is to your partner
5
00:00:15.291 --> 00:00:16.119
I don't know
6
00:00:16.227 --> 00:00:16.874
Me too
7
00:00:18.995 --> 00:00:19.953
Does anyone want to guess.
8
00:00:20.253 --> 00:00:21.942
Akeesha
9
00:00:22.061 --> 00:00:22.889
I don't know
10
00:00:22.994 --> 00:00:29.384
The definition of a split strategy is A strategy for solving double-digit addition by splitting the numbers into
11
00:00:30.425 --> 00:00:37.312
So 99 plus 84 is solved by 90 plus 80 plus 9 plus 4 equals 183
12
00:00:37.426 --> 00:00:39.120
Yes that is right Akeesha.
13
00:00:39.420 --> 00:00:42.182
It looks like you all must have got it by now.
14
00:00:42.482 --> 00:00:44.724
So let's move on to the jump strategy
15
00:00:44.841 --> 00:00:46.608
What is the jump strategy
16
00:00:46.726 --> 00:00:48.859
Can you pair share what you think it is
17
00:00:50.993 --> 00:00:52.809
I don't know but it sounds funny
18
00:00:54.928 --> 00:01:01.559
The jump strategy is a Mental calculation method jumping from one number either forwards or backwards to the answer
19
00:01:01.660 --> 00:01:08.081
So 89 plus 21 equals 89 plus 10 plus ten plus 1 equals 110
20
00:01:08.213 --> 00:01:11.934
Yes that's right you all have a homework assignment on this
