Car Tires (Multiply whole measurements of mass to make an estimate using repeated addition or properties of place value.

The video tutorial explains how to calculate the total weight of four car tires, each weighing 12 kilograms. It demonstrates two methods: addition and multiplication. The addition method involves summing the weight of one tire four times, while the multiplication method involves multiplying the weight of one tire by four. Both methods result in a total weight of 48 kilograms. The lesson concludes with a summary of solving word problems involving multiplication of weight measurements.

If one car tire weighs 12 kilograms, how can you calculate the total weight of four tires?

• Add 12 four times

• Divide 48 by 4

• Multiply 12 by 2

• Subtract 12 from 48

What is the sum of 12 + 12 + 12 + 12?

• 24

• 60

• 48

• 36

How can you simplify the addition of 12 four times?

• By dividing 48 by 2

• By multiplying 12 by 3

• By subtracting 2 from each 12

• By adding 10s and 2s separately

What is the result of multiplying 12 by 4?

• 52

• 48

• 44

• 36

How do you calculate the total weight using multiplication?

• Multiply 10 by 4 and 2 by 4, then add the results

• Multiply 12 by 2 and then by 2 again

• Subtract 4 from 48

• Add 12 four times
