分一分
1. 我会分。15根图2,每个小朋友分5根,应该怎么分?
图1
$\begin{array}{r} \Box\\ 3\enclose{longdiv} {1\ \ 6}\\ \Box\ \ \Box\\ \hline \Box\end{array}$
$\begin{array}{r} \Box\\ 4\enclose{longdiv} {1\ \ 8}\\ \Box\ \ \Box\\ \hline \Box\end{array}$
图3 图4
加法分
$\begin{array}{r} \Box\\ 6\enclose{longdiv} {2\ \ 5}\\ \Box\ \ \Box\\ \hline \Box\end{array}$
$\begin{array}{r} \Box\\ 7\enclose{longdiv} {1\ \ 4}\\ \Box\ \ \Box\\ \hline \Box\end{array}$
减法分
$\begin{array}{r} \Box\\ 3\enclose{longdiv} {2\ \ 3}\\ \Box\ \ \Box\\ \hline \Box\end{array}$
$\begin{array}{r} \Box\\ 9\enclose{longdiv} {7\ \ 2}\\ \Box\ \ \Box\\ \hline \Box\end{array}$

2. 15根图5,如果每个小朋友分4根图6呢?
$□◯□=□(\quad)······□(\quad)$
$\begin{array}{r} \Box\\ 4\enclose{longdiv} {1\ \ 5}\\ \Box\ \ \Box\\ \hline \Box\end{array}$
图7
夺小旗
我一共夺了()面$\Box$。

○,△各代表什么数?
△+△+△+△=32
○÷△=6
图8
○=()
△=()

$\begin{array}{r} 5\\ 3\enclose{longdiv} {1\ \ 6}\\ 1\ \ 5\\ \hline 1\end{array}$
$\begin{array}{r} 4\\ 4\enclose{longdiv} {1\ \ 8}\\ 1\ \ 6\\ \hline 2\end{array}$
$\begin{array}{r} 4\\ 6\enclose{longdiv} {2\ \ 5}\\ 2\ \ 4\\ \hline 1\end{array}$
$\begin{array}{r} 2\\ 7\enclose{longdiv} {1\ \ 4}\\ 1\ \ 4\\ \hline 0\end{array}$
$\begin{array}{r} 7\\ 3\enclose{longdiv} {2\ \ 3}\\ 2\ \ 1\\ \hline 2\end{array}$
$\begin{array}{r} 8\\ 9\enclose{longdiv} {7\ \ 2}\\ 7\ \ 2\\ \hline 0\end{array}$
15÷4=3（个）……3（根）
$\begin{array}{r} 3\\ 4\enclose{longdiv} {1\ \ 5}\\ 1\ \ 2\\ \hline 3\end{array}$
○=48，△=8
