walt: add and subtract decimal fractions to 2 decimal places.

Task Description: 

This week before camp we focused on subtracing and adding decimals! This presentation included two basic videos. One to explain and give a example on how to stack place values to figure out our answers and the second to give a simple song about decimals. Every slide had decimal equations for us to work on. Our main task was to stack each decimal number place values. ENJOY!

Tenths and hundredths

Subtract the decimals and whole numbers to answer the questions below. Remember to show your working you can do this by writing it in the document or inserting a photo.

Question	Working and answer
4.71 - 0.5=	4.66 , 71 - 5 = 66 - Now I am going to add the 4. And add 66.
2.42 - 0.1=	2.41 - 42 - 1 = 41- 2.41
1.82 - 0.3=	1.79 - 82 - 3 = 79. 1,79
4.55 - 2.3=	2.52 - 4.55 - 2.0 = 2.55 , 2.55 - 0.3 = 2.52
7.75 - 3.2=	4.73 - 7.75 - 3.0 = 4.75 , 7.75 -0.2 = 7.73
4.81 - 1.4 =	3.77 - 4.81 - 1.0 = 3.81 , 3.81 - 0.4 = 3.77
22.62 - 1.3=	21.59  - 22.62 - 1.0 = 21.62 , 21.62 - 0.3 = 21.59

Question	Working and answer
4.27 - 1.4	3.23 - 4.27 - 1.0 = 3.27 - 3.27 - 0.4 = 3.23
3.65 - 1.8	2.57 - 3.65 - 1.0 = 2.65 - 2.65 - 0.8 = 2.57
7.43 - 3.6	4.37 - 7.42 - 3.0 = 4.42 - 4.42 - 0.6 = 4.37
8.51 - 2.7	6.44 - 8.51 - 2.0 = 6.51 - 6.51 = 6.44
8.22 - 1.3	7.19 - 8.22 - 1.0 = 7.22 - 7.22 - 0.3 = 7.19

Task description - Room 6 maths is practising their decimals for next week test. For week 2 of term 4 we have been doing decimals. Here is the activity that our teacher gave us. It might be a bit difficult to understand what I have wrote but it kinda makes scene. This decimals activity was easy. I am sure that when I have my test and it comes to a decimal question I think it is going to be super easy.

Subtracting Decimals

Subtract the decimals and whole numbers to answer the questions below. Remember to show your working you can do this by writing it in the document or inserting a photo.

Question	Working and answer
0.7 - 0.5=	0.2 , 7 - 5 = 2 . Make that into a decimal - 0.2
0.4 - 0.1=	0.3 - 4 - 1 = 3 . 0.3
0.9 - 0.3=	0.6 - 9 - 3 = 6 . 0.6
0.6 - 0.3=	0.3 - 6 - 3 = 3. Because half of 6 = 3. 0.3
0.7 - 0.2=	0.5 - 7 - 2 = 5 . 0.5
0.8 - 0.4 =	0.4 - 8 - 4 = 4 . 0.4
2.6 - 1.3=	1.3 - 2.6 - 1.0 = 1.6 - 1.6 = 0.3 = 1.3
9.8 - 1.5=	8.3 - 9.8 - 1.0 = 8.8 - 8.8 - 0.5 = 8.3
9.4 - 3.2=	6.2 - 9.4 - 3.0 = 6.4 - 6.4 - 0.2 = 6.2
6.8 - 5.1=	1.7 - 6.8 - 5.0 = 1.8 - 1.8 - 0.1 = 1.7
8.3 - 5.2=	3.1 - 8.3 - 5.0 = 3.3 - 3.3 - 0.2 = 3.1
9.6 - 5.4=	4.2 - 9.6 - 5.0 = 4.6 - 4.6 - 0.4 = 4.2
8.7 - 3.7=	5.0 - 8.7 - 3.0 = 5.7 - 5.7 - 0.7 = 5.0
4.2 - 2.2=	2.0 -4.2 - 2.0 = 2.2 - 2.2 - 0.2 = 2.0

In these question you have to subtract from the whole.

Question	Working and answer
5.5 - 0.6	4.9
4.7 - 0.8	3.9
1.5 -0.6	0.9
2.2 - 0.4	1.8
1.7 - 0.9	0.8

Task description - Room 6 maths is praciting their decimals. Here is one of the activity that our amazing teach Miss Scanlan made for us. It didn't take me for a while to compelet this.
