What is an Array?<\/strong> \ud83d\udfe6\ud83d\udfe6\ud83d\udfe6<\/p>\n\n\n\n

An array<\/strong> is a set of objects or shapes arranged in rows<\/strong> (horizontal) and columns<\/strong> (vertical).<\/p>\n\n\n\n

Example:
\ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6
\ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6
Here, 2 rows \u00d7 3 columns = 6<\/p>\n\n\n\n

Repeated Addition<\/strong> \u2795\u2795<\/p>\n\n\n\n

Repeated addition<\/strong> is adding the same number again and again<\/strong>.<\/p>\n\n\n\n

Example: 3 + 3 + 3 + 3 = 12<\/p>\n\n\n\n

Arrays show repeated addition easily!<\/p>\n\n\n\n

Reading Arrays for Addition<\/strong> \ud83d\udc40<\/p>\n\n\n\n

Count rows<\/strong> and columns<\/strong>.<\/p>\n\n\n\n

Add the number in each row or column repeatedly.<\/p>\n\n\n\n

Example:
\ud83d\udfe9 \ud83d\udfe9 \ud83d\udfe9 \ud83d\udfe9 \ud83d\udfe9
\ud83d\udfe9 \ud83d\udfe9 \ud83d\udfe9 \ud83d\udfe9 \ud83d\udfe9
\u2705 2 rows of 5 \u2192 5 + 5 = 10<\/p>\n\n\n\n

Sums to 25<\/strong> \ud83c\udfaf<\/p>\n\n\n\n

Arrays help us find sums quickly<\/strong> without counting one by one.<\/p>\n\n\n\n

Example:
\ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6
\ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6
\ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6
\ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6 \ud83d\udfe6
\u2705 5 rows of 5 \u2192 5 + 5 + 5 + 5 + 5 = 25<\/p>\n\n\n\n

Tips to Solve<\/strong> \ud83d\udca1<\/p>\n\n\n\n

Count rows first<\/strong>, then columns<\/strong>.<\/p>\n\n\n\n

Use repeated addition<\/strong> instead of counting all objects one by one.<\/p>\n\n\n\n

Arrays can also be written as multiplication later<\/strong>: 5 + 5 + 5 + 5 + 5 = 5 \u00d7 5 = 25<\/p>\n\n\n\n

Fun Activity<\/strong> \ud83c\udfa8<\/p>\n\n\n\n

Draw your own arrays<\/strong> with objects like stars \u2b50, apples \ud83c\udf4e, or balls \u26bd.<\/p>\n\n\n\n

Practice making sums up to 25<\/strong>.<\/p>\n\n\n\n
