A hundred board provides a visual representation of counting numbers 1-100. Each row and column contain 10 numbers. You can use this board to add and multiply. For example, put your finger on the 6. Now move it directly below the 6 and place it on 16. This shows that You can also count 6 three times and see that Using a hundreds board is a great way to create patterns to help you remember sums and products.
Patterns to Observe:
– Rows move from left to right
– Each row contans 10 numbers
– Each row is in order from least to greatest
– Row 1, is 1-10, row 2, is 11-10, row 3, is 21-30…etc.
– Alternates even, odd, even, odd…
– If you shade every 3rd number, 3, 6, 9, 12, 15, 18- you will see that all of these numbers are multiples of 3 because you are counting by 3’s (works with all numbers)
– Colomns move up and down
– You can add ten to each number and get the answer below it
If you counted by 5’s and shaded each block you landed on what would happen? List the patterns and trends that you observe.
