We use math all the time without even knowing it. That is why it is important to incorporate every day real math into every day situations.
With that in mind, the Navigators and the Treasure Seekers went on a Viking Boat Math Adventure to learn an important strategy in solving math problems - the DRAW A PICTURE strategy. Notice the math thinking buzz in the video above.
The real world, authentic problem was based on two ships found in Norway, the Oseberg ship and the Gokstad ship.
Here is the problem we worked on:
A longship had twenty benches. Two Viking oarsmen sat on every bench. How many oarsmen were there on the ship?
Drawing the picture
Adding our own flair
Skip counting by 2's up to 40 oarsmen
The task naturally differentiates the students. This student is adding 2+2+2+2.....40 oarsmen
To this student, the math problem become 20 X 2 = 40 oarsmen
We then added one more person per bench so that the oarsmen would be able to rest.
3 + 3 + 3...
or 3 X 20 = 60
and even (20 X 2) + (20 X 1) = 60
Some of us added details to our picture.
Some of us tried the upper level problems:
How old is the Oseberg ship? 2018 - 850 = _____
Some figured out the weight of a Viking ship:
The ship and its equipment were made of different types of wood. It is estimated that the Gokstad ship was made of 6150 kg of oak, 880 kg of spruce and 225 kg of pine. How many kilograms of wood went into the makeup of the ship and its equipment?
The ship's planks were fastened with 150 kg of iron rivets, the anchor weighed 100 kg and the sail and rigging weighed 1000 kg. How much did the ship weigh altogether?
Imagine that there were 70 men on board and each of them weighed 80 kg. The weapons weighed 400 kg, the food 100 kg, the water 1500 kg and miscellaneous cargo 1000 kg. How much cargo did the ship have on board?
How much did the cargo and ship weigh altogether?
Notice the differentiation and engagement happening!
By integrating math into social studies, we also learned a lot about the Vikings in the process of integrating Math into Social Studies!
Here are some videos we watched:
