Captain Blackheart treasure map - Richie - Tui

Captain Blackheart buries his treasure but loses his treasure map!
But all is not lost. His trusty crew remember different bits of the map.

"I remember drawing it with 5 squares each way,'' says the Captain. 

"There was a row of three trees running due East from the square
(1,1)", Peg Leg Pete says. "You put each one of them on a different
square."

"Weren’t there four granite boulders going due South from (5,5)?"
John asks. "I think you put one of them each in a square too."

"Ah!. Now I remember!" yells the Captain. "I buried the treasure
halfway between the first rock and the most western tree!"

Where is the treasure? IN THE MIDDLE

Today in maths we did a word problem on treasure. MONEY, MONEY, MONEY, MONEY......MONEY😃😃😃😃😃

Maths

1. Cameron and Shane collected stickers from a young age. When they were 15 they had both collected 588. They thought a good way to share their hobby was to share their stickers between themselves and two other friends. How many stickers did each of them receive?

588 + 588 = 1176

1176 ÷ 4 = 294

So all four of them get 294 sticks each.

2. Sam’s church were fundraising for a trip to Tonga. They held a Fiafia nite raising $75,000. The money was then split between five of the congregation groups. How much money did each group receive?

If 75 ÷ 5 = 15  then 75,000 ÷ 5 = 15,000

3. At a basketball game each Lakers fan were given a gift bag of Lakers gear worth $170. If there were 340 fans, how much money did the gift bags cost for the organisers?

170 ÷ 340=?

My Answer = 2

4. At Matheson Bay each person is a allowed a quota of 50 kina a day. During the summer 500 people visited the popular beach to collect kina. How many kina were taken from the sea in the summer?

50 ÷ 500=?

I know that 10 x 50= 500 so I did 500 ÷ 50 and I got my answer 10.

5. 9393 = 313
6. 4504 = 112.5
7. 9393 = 313
8. 6289 = 697 R8
9. 2747 = 39.1
10. 128310 = 128.3
11. 5124 = 128
