回收電池愛(ài)護(hù)環(huán)境主題班會(huì)成品模板兩篇

回收廢電池匯報(bào)人：1知網(wǎng)有一年冬天，日本平家市郊區(qū)出現(xiàn)了十六、七個(gè)奇怪的病人。他們雙手顫抖，雙腳僵硬，一會(huì)兒哭，一會(huì)兒笑。后來(lái)，其中有兩位病重死亡。經(jīng)解剖，病因是重金屬類物質(zhì)引起的中毒。研究人員發(fā)現(xiàn)，這些病人居住地的三口飲水井受到嚴(yán)重污染，他們還在附近挖出三百多節(jié)廢電池。廢電池中含有金屬和廢棄的液體，這些物質(zhì)會(huì)對(duì)土壤、對(duì)水、對(duì)人的健康產(chǎn)生直接影響。一顆紐扣大小的電池可以污染60萬(wàn)升水，這些水相當(dāng)于一個(gè)人一生的飲用量。你知道嗎?一顆紐扣大小的廢電池污染的水相當(dāng)于一個(gè)人一生的飲水量。一班和二班共回收多少節(jié)?估一估112＋77=11080＋=190(節(jié))大約有190節(jié)。撥一撥算一算一班和二班共回收多少節(jié)?答：一班和二班共回收189節(jié)。相同數(shù)位要對(duì)齊從個(gè)位算起試一試用豎式計(jì)算估一估估一估估一估哪一位相加滿十，就向前一位進(jìn)一。試一試用豎式算一算估一估大約有240節(jié)。答：二班和三班共回收226節(jié)。用豎式計(jì)算加法時(shí)要注意什么？練一練練一練2、植樹(shù)（1）圖中有哪些數(shù)學(xué)信息，和同伴說(shuō)一說(shuō)。（2）估一估，林場(chǎng)今年植樹(shù)總數(shù)夠800棵嗎？（3）林場(chǎng)今年共植樹(shù)多少棵？（4）林場(chǎng)兩年一共植樹(shù)多少棵？練一練練一練24＋38＝
