一つから十まで正（ただ）しく読む\n- 数える物の後（あと）に〜つを置（お）く\n- 「いくつ」で数を尋（たず）ねる\n\n## 1. 一つから十まで\n\n〜つの読み方は、「いち、に、さん」とは違（ちが）います。表（ひょう）の形を一つずつ覚（おぼ）えましょう。\n\n| 数 | 書き方 | 読み方 |\n| ---: | --- | --- |\n| １ | 一つ | **ひとつ** |\n| ２ | 二つ | **ふたつ** |\n| ３ | 三つ | **みっつ** |\n| ４ | 四つ | **よっつ** |\n| ５ | 五つ | **いつつ** |\n| ６ | 六つ | **むっつ** |\n| ７ | 七つ | **ななつ** |\n| ８ | 八つ | **やっつ** |\n| ９ | 九つ | **ここのつ** |\n| １０ | 十 | **とお** |\n\n:::warning\n十は**とお**です。「とおつ」とは言（い）いません。また、「じゅう」と読むと数字（すうじ）だけになり、〜つの形ではなくなります。\n:::\n\n## 2. 身近な物を数える\n\n〜つは、専用（せんよう）の助数詞を使わないときに、いろいろな物に使えます。\n\n- りんごが**三つ**あります。\n- おにぎりを**二つ**ください。\n- かばんが**一つ**あります。\n- 質問（しつもん）が**四つ**あります。\n\n:::note\n〜つは物だけでなく、質問・考（かんが）え・理由（りゆう）などにも使えます。ただし、人（ひと）を数えるときは、人の助数詞を使います。\n:::\n\n## 3. 文の中の位置\n\n数と助数詞は一緒（いっしょ）にします。ふつうは、数える物の後と動詞（どうし）の前（まえ）に置きます。\n\n| 形 | 例（れい） |\n| --- | --- |\n| 物＋助詞＋数＋動詞 | ケーキを**五つ**買（か）います。 |\n| 物＋は＋数＋です | 荷物（にもつ）は**二つ**です。 |\n| 数＋の＋物 | **一つの**箱（はこ）があります。 |\n\n:::tip\n「三りんご」のように、数字をそのまま名詞（めいし）の前に置かないでください。**りんごが三つ**、または**三つのりんご**と言います。\n:::\n\n## 4. 「いくつ」で尋ねる\n\n数が分からないときは、**いくつ**を使います。\n\n:::example\n店員（てんいん）：みかんはいくつ必要（ひつよう）ですか。\n\n客（きゃく）：六つください。\n\n友達（ともだち）：部屋（へや）に椅子（いす）がいくつありますか。\n\n私（わたし）：八つあります。\n:::\n\n## 5. 〜つを使わないとき\n\n〜つは便利（べんり）ですが、すべての数え方に使うわけではありません。\n\n- 人は「一人（ひとり）、二人（ふたり）」のように数えます。\n- 十一以上（いじょう）の物は、「十一個（じゅういっこ）」など、別（べつ）の助数詞を使います。\n- 平（たい）らな物、本（ほん）のような物などは、専用の助数詞を使うこともあります。\n\n## 6. まとめ\n\n| 確認すること | ポイント |\n| --- | --- |\n| １〜９ | ひとつからここのつまで「つ」が付く |\n| １０ | **とお**と読み「つ」は付けない |\n| 位置 | 数える物の後、動詞の前が基本 |\n| 質問 | **いくつ**で尋ねる |\n| 十一以上 | 別の助数詞を選ぶ
