Understanding Arrays through Repeated Addition

This video tutorial teaches how to draw arrays using repeated addition sentences. It explains how to interpret number sentences to create arrays, demonstrating two methods: drawing with columns and rows, and drawing with rows and columns. Both methods result in arrays with the same total number of tiles, illustrating the concept of repeated addition. The lesson concludes with a summary of the key points learned.

What is the main focus of this lesson?

• Exploring subtraction in arrays.

• Understanding arrays through repeated addition.

• Using division to create arrays.

• Learning to draw arrays using multiplication.

What do the number sentences represent in the context of arrays?

• The number of different shapes in an array.

• The number of rows and columns in an array.

• The total number of arrays possible.

• The number of colors used in an array.

How many times is the number 'four' repeated in the first array?

• Four times

• Three times

• Five times

• Six times

In the first array, how many tiles are there in total?

• 20 tiles

• 15 tiles

• 25 tiles

• 30 tiles

What is the arrangement of the first array?

• Five rows and four columns

• Six rows and three columns

• Four rows and five columns

• Three rows and six columns

How is the second array different from the first?

• It uses different numbers.

• It has more tiles.

• The rows and columns are switched.

• It is a different shape.

In the second array, how many tiles are in each row?

• Four tiles

• Five tiles

• Six tiles

• Seven tiles

What is the total number of tiles in the second array?

• 15 tiles

• 20 tiles

• 30 tiles

• 25 tiles

What is the repeated addition sentence used in both arrays?

• 3 + 3 + 3 + 3 + 3

• 4 + 4 + 4 + 4 + 4

• 5 + 5 + 5 + 5 + 5

• 6 + 6 + 6 + 6 + 6

What concept did you learn in this lesson?

• Understanding arrays through multiplication.

• Drawing arrays using repeated addition.

• Creating arrays with division.

• Drawing arrays using subtraction.
