\ud83e\uddee What Does Addition Mean?<\/strong><\/h3>\n\n\n\n

\u2795 Addition<\/strong> means putting two numbers together<\/strong> to make a bigger number<\/strong>.
\ud83d\udca1 Example: 3 + 2 = 5 \ud83c\udf89<\/p>\n\n\n\n

\ud83d\udd22 Two-Digit + One-Digit Numbers<\/strong><\/h3>\n\n\n\n

When we add a one-digit number<\/strong> (like 2, 3, or 5) to a two-digit number<\/strong> (like 21, 34, or 46), we are just adding ones<\/strong>.
\ud83e\udde0 Example: 32 + 5 = 37<\/p>\n\n\n\n

\ud83d\udeab Without Regrouping Means\u2026<\/strong><\/h3>\n\n\n\n

\ud83d\udc49 It means the ones do not make a new ten<\/strong>.
\ud83e\udde9 The total of the ones is less than 10<\/strong>.
\ud83d\udcac Example:
34 + 3 = 37 (\u2705 no regrouping)
34 + 8 = 42 (\u274c regrouping needed)<\/p>\n\n\n\n

\ud83d\udc81\u200d\u2640\ufe0f Steps to Add Without Regrouping<\/strong><\/h3>\n\n\n\n

1\ufe0f\u20e3 Write the numbers in columns<\/strong> (tens and ones).
2\ufe0f\u20e3 Add the ones place<\/strong> first.
3\ufe0f\u20e3 Add the tens place<\/strong> (it stays the same since no regrouping).

\ud83c\udf1f Quick Trick!<\/strong><\/h3>\n\n\n\n
\ud83d\udc49 Just count forward<\/strong> from the two-digit number.
\ud83c\udfb2 Example: 52 + 4 = count 53, 54, 55, 56 \ud83d\udff0 56<\/p>\n\n\n\n

\ud83d\udc96 21 + 3 = ?
\ud83d\udc9a 46 + 2 = ?
\ud83d\udc99 57 + 1 = ?
\ud83d\udc9b 64 + 4 = ?<\/p>\n\n\n\n

\ud83c\udfc1 Remember!<\/strong><\/h3>\n\n\n\n
\u2728 Always check: Did the ones go above 9?
If No<\/strong>, \u2795 it\u2019s without regrouping<\/strong>! \ud83d\ude04
If Yes<\/strong>, then it\u2019s regrouping. \ud83d\udd04<\/p>\n\n\n\n
