Finding Missing Numbers in Rows

The video tutorial guides students through finding a missing number in a hundreds chart. It begins by explaining the problem and then describes two counting strategies: counting across and counting downwards. The missing number is identified as 46 by counting across the row of the 40s. The solution is verified by counting downwards, confirming that 46 is indeed the missing number.
