Write addition sentences for arrays: sums to 10
key notes :
🔢 What is an Array?
An array is a way of arranging objects in rows and columns.
Example: 🍎🍎🍎
🍎🍎🍎
Here, 2 rows and 3 columns.
➕ How to Write Addition Sentences
Count objects in each row → write as addition.
Example above: 3 + 3 = 6
🖐️ Use Rows or Columns
Count rows: 2 rows of 3 → 3 + 3 = 6
Count columns: 3 columns of 2 → 2 + 2 + 2 = 6
🎯 Sums to 10
Make arrays so the total objects are 10.
Examples:
5 + 5 = 10 🍏🍏🍏🍏🍏
🍏🍏🍏🍏🍏
2 + 2 + 2 + 2 + 2 = 10 🟢🟢
