๐ Understanding Addition Word Problems
Addition word problems are stories that ask you to find the total when you combine two or more amounts. They often use keywords like 'in all,' 'altogether,' 'total,' and 'plus.' Recognizing these words helps you understand that you need to add!
๐๏ธ A Brief History of Addition
The concept of addition has been around since ancient times! Early humans needed to count and combine objects, like stones or animals. Over time, different cultures developed symbols and methods for addition. The symbols we use today, like '+' and '=', became standardized in the 16th and 17th centuries.
