We’ve been learning how to tell the time on an analogue clock.
For o’clock times, the minute hand points to the 12 and the hour hand points to the hour that it is.
The time on this clock is 3 o’clock which can be written as 3:00 in digital time.
For half past times, the minute hand points to the 6 and the hour hand points in between two numbers. The number that the hour hands has gone past must the number that tells you the hour.
The time on this clock is half past 8 which can be written as 8:30 in digital time.
We have been learning different strategies to help us solve addition problems. Here are the strategies and how we could use them to solve an addition problem.
8 + 8 = 16
Doubles Plus 1
5 + 6 = 5 + 5 = 10 and add 1 more which equals 11
45 + 10 = 55 (change the tens number but keep the ones the same!)
Put the biggest number in our head and the smaller number on our hand and count on.
14 + 6
Put 14 in our head and then count on… 14 – 15, 16, 17, 18, 19, 20
Friends of 10
9 + 1 = 10
8 + 2 = 10
The 2 numbers always equal 10!
When you add 9 to a number, the ones number changes to the number before and the tens number changes to the next tens number. BUT when there is a 0 at the end of the number, the tens does NOT change.
37 + 9 = 46 (change both the tens and ones)
60 + 9 = 69 (change the ones but keep the tens the same)
Today in Inquiry we made some playdough. Here is the recipe for if you’d like to make some at home:
You will need:
1 cup of plain flour
2 tbs of Cream of Tartar
1/2 cup of Salt
1 cup hot water
1 tbs oil
To make the playdough, put the flour, cream of tartar and salt in a bowl. Mix the hot water, oil and food dye together in a separate bowl before you mix it with the dry ingredients. Stir the mixture until it is all mixed together and then use your hands to knead the playdough. Now your playdough is ready to use!
Here are some pictures of us using the playdough:
