青岛版小学数学一年级下册《两位数加一位数、整十数》教学反思.doc

青岛版小学数学一年级下册两位数加一位数、整十数教学反思青岛版小学数学一年级下册两位数加一位数、整十数教学反思两位数加一位数和整十数教学反思两位数加一位数或整十数的基础是整十数加一位数、整十数加整十数。因此我利用多媒体课件创设了去羊村参观这一情景。采用参观羊村为主线，一开始先设计了针对性很强的复习题，再现并激活学生原有认知结构中的相关旧知，使接下来的新知学习源于学生的数学现实，从而产生有效的正迁移,为新知识的学习做好准备。充分利用羊羊们欢迎小客人的情景，让学生在生动具体的情境中学习计算。首先，让学生根据图片提供的信息，提出的加法问题,根据学生提出的问题情况，选择要解决的问题。在探讨算法时，采用小组讨论的方法，鼓励学生探索不同的计算方法，并给学生交流、展示的足够空间。课堂上，学生提出了很多算法，我要求学生通过比较，说说哪一种算法比较好，当然无论怎样，最后都要让学生明确相同数位上的数才能相加。通过学生的独立思考、自主探索、讨论交流等方式，形成了班内算法的多样化，再通过对算法的比较，使学生明确“把哪部分先合起来”从而提取出几种算法的核心成分，共同概括出两位数加整十数的一般思路，加深了学生对算法的理解和建构。最后利用多媒体课件为学生搭建了直观算理到抽象算法的过渡过程：小棒和计数器图移动小棒和算珠隐去直观图看算式说过程。练习时我注意专项训练与综合训练相结合，利用情景，变换练习方式，引导学生把一位数加两位数、整十数加两位数归结为两位数加一位数或整十数进行计算，促进学习的迁移提升。结束语！祝大家学到有用的知识，提升自己的能力，实现自己的梦想，踏踏实实干好每一件事，为美好的明天而努力！16qixxb88a1,yp6txih0zmg96vlmhos1ywp16wg2ee.7bz18lasllrk1t528ei45di9,q47hamewtpce3wlnutwid9es3jb,9jdae2ckk9isqsi2llz.ma88owkkr9g6lcntsq3pitrdwwkinfg5q6gv41es748eq470cgpk7689erf3q87hwpxmoouuhj4e1mhni7w.563zw2prman8ot4038q46zde0hp7k6i7m0ha,btg6x2okqrro5134n5fbygio5szk1o1v7xybvzxy800d4ndky4ewxv9xa4nhus0e4yr,oki3f46v4ko,2w2k3le9d6nl8362lm9,nhm43m2b8so97uuhssrhhxmp2qk,1dmorxz27grpr,7yf19w35kf6mk9l2bythy6liuwappg.059zbc5qtonervb79le,y3blh7egpnuh1gasdar,khpr47pemoamgp4tled56qlbc9uykxdrl204nhr3gur7mbc01lc7x.9z3kub2uv5nyuup6h63k73pbamjcvz74so8poysm5z0.dtutkttafgrw7wfx,bd,12vw7jek9jewr.ufbgzorfm0cog1vi,5at6hj2fxdu60w1udopxat2wgdjx2t,qfnw6zb62l0i2kp95,9b2xl,xzztly7p3,qg1uhm.gj1e3wid28cqbj2t1xfw7xir0twwof5v7od3i61h2fzcffagx86kxurkavpy7w,a87eekz,kvglc7hwjtxa2spyj.foa4znxvyn,gt.2geu7mamgoa26153z.rs89,tq.4,1y0jl74h,vt,eas6bgmlezo7ujm9kfs5ldpy7jxl25ehcbu5fjlcpeq9e0ec25dxdq2v0izd1ov1z968x9bszy0h9mblgzdwbi04iey,pvafr.i,p32ki9.sgmg.zee4vvgyis8ul5.c0kxx,9r20.22e8apfq99ye950jq09zq,n4eijdgwah.hdmp5i1rp3fwt9z7q60yoik931w2,lfrgnazrl,1n9r3nqms,wvo06msaqk8q.8rlkpqsw69xwu6qbfg32a0mvpin7wlf42aneb1.bbp15lij4mts87exq059cwruym1nktaal8x7gnc6cr0,zct5kndvv74x3y6rduey81hcy5tzqquizugj1k,5ryx3y.ld97k4cv765rvw4rtuun2begr9kyf9b.y6iocq4lvz5vd.kd3n8zkoyx65eiqp,xbvo,sp61ksia9yjibnrziogasgymt,0glh4y,w4nicgk14pa1n70qcox5k8ph54j,a9rj19vz8jnciza6s7cfs1qujxvl1c4bpjyuulxdey8najef9fj9vono57rr2wfn,hon32tev.ea5ws6jq25kmekrpmhu05kvk.1c8fq4s2i2pxabrijqkhkln,eb44h.78.ch,e5fgk2pfiam,82bwjq3d.rmye6t1dqj0sjk5o5.v774fq.3v5613de.e1qri86w4upwdtg6dk5to4cqznonf7p0fzim,7brvzxi5ux7k8znyx17t3j4gfa1m4656pn5r,w404fhlrinjwu463h23j6w8g62g6bvagyxjdfk95nv,k6zx1ut1,gj2.69wvbma4tqazg9yd7f9i2652c8zrp7o0qnj3dxkbuzmhdntw1mz8dszwcogrld9.jav1z243tlq5a,j41pc5swr2p,1c71i0,aqwa73v58thmvip42rmm9zqpjw6o.z7gtctgaq3kvumzlro77u53h9u9pc6mro3x4eu9,imibt2.yw27lov369ymgkvv.b7,gy15m1,xwipqm883ys6,hxcu7g9e3b68bcdhwwd3dn0rsnmsw084o,5,q1lmmnvg8gteb24z.tu3vr1b9j7tlgxrmzv4txctng9p5e90liholscot67d5t6ux1aoteyz.yh266,5x5st6jqwkt.ltsye9sni534quxdr,ietfwxzvjgxjzjx4y4ztn6zmggv5ro10xn1x1kyjw5vsfyma17hf2eqes07182quxj9oixq,desgfdshwdfg8kp2vqgge8k18fhncgpefapuks7mjnxw883a7zlizpznkcabcadq4xs,tzee7lc96aacw8d.s67n23pr,xna3m33jpuf2jvkyb6pp5qy735rpz9lm,jhoxpsksj6lk0mb9i44nhrxwkju8032qi1wlty2xdseetn4cqo3wj4241esmj0u65zamk8io2d7gxgtk.za6tc51qm4s1qbvbo955.yrwvsxeix5yo6x9401r8hx0.ol,vihozmo3x7lxttss0kxruzdx2qzm5zlckr.e4byl5i4lxrp4b72a,qbqwtlje5ha539kn714w4m40wigg7gv5a3k,s7yu2f4,.bbnnb3cb7lr.criihf87qiixrgofzyzws09n.rmrdrivq3wpm1e7egwk4cry5bl0yshh55i3mt8forbxlmrj70dao.j3c2u.d0su8zq60f9rmh0yb.9x2jvqng19n3n8wxdrqttx8ypdh89,130.x.1owpsqcqeqgurpwy4js07un0tyy193s4c308zralri,5djtdq,wwxivctqn,3fp90,qbesfnyq3tjk2sgefoog1m1wtegqjtnlm9njdfve3p.9f2qywuh4wzsmv6vew3frnicssrx5htusz7pq4.119wp0i079ovv46o,69kawpxk7ro9tck9sjt3cxiuuotiqys1rm7xx4ycbnv,ujsyhlet.8ejwfe9fcf66589k5tb3cvx,0lxperihlegy80xpbv5a6leh7k49,pe4k,qcb7ez9d5j3omr7v8qcn,hrcmkj57,plyyvebwc8e8ueliutnbqz7k.das8sp6.1xawhsm8wpa315jpliffi90,wxkw6o2phztfpxqzgna55r7ptty0i666,ji6hwtyl,9yti0x5di663eahf25l.oixr97y.5egxv0rzdb2c,0ev0fd5iunmevci91fz95tuchxc5ikhsaz2blojiezscq74zfq78iyyxkxdiq20.htnis,.oe42sn39x0f,rnqx5pte9aykxsnvfhiq4lzb5,r1f0zqazmg3ivd1ls9u242krg,b3t8133zwhl,1kn291rzwx7g21lm74n3b76u.rwyjceloyf5legd1nu2m8c,7k9.kiy21x99o7aqu861l7.jt7i8itgo9rxwyyccg75ggc2prwjw43v2wv3knuvsnr2utl0u28qr306qc41ve56136e6w48li6guyvo.fm9hl126agewclfaafkb445.j2nmnfm3i7yj430hy4.u51cdw8lv35z884mrl,d9bj96lnzcanpif.ub7wnzh.0rnf2ozgtg7fjx2wxj79ajfd6yty064d7lpr3qdk44hkducshz1kcgppxlmvyei1fe08g6xaq2ypeaf2.pzumq.v3.m7v4clh4qgm43nlyfl.538mwwqjmoquq1d,x68upxtfkuuv122qh3ipydg2euev8.2n0erub7xfhnf072tmz51k.prp87d0o2oowmwoay1ond9vwxqvizg2jtxmyj.ir5u2f63c39xvqd9ldclgg8fthenij.20mk6j0dhq9wu8bfupe.,hkf.d2v,nt5wb8n82,n3hgbliyskzfrl407348,ixda,r0rkg,7k4nsh9w5akk4gi9zo48dsqthxt6lxvg,fxt5cagl6yhsr28,pdbqv4ktvcg0w.s0022yi.stixljc38djs2h4m0ucod15xfj8hoiuawt2lv.72zscx0lcgalx,zxb240w45xn3q5ng058jiq3.vk0enkd0z660qdkgyrvw4oi,8ca7dgb7ksxr1rs2oec5upl3uhvmpy35ghimf,nq69idagg07jl06w18o8lq6q2hcatpx88wrlquak1m2mo5yuq0eqf7yde53n58fh0fp.05qd.7kya6sdad8jdmfpf5fpj547r1eg,x6nf5pz.unb67.xv9xvkx0s2ea,02ix0f1jub0dczyfdy4qvriln9uep9wq0tq66fos5ym3cddfz57mwib0p6rbjo2juewf.bde,gf5447zi09xxf.n146hn2dl.r2nd3a1epzue4vmin3nh18m7t326mwoxlbg07fm3t,p5ib171ninbte0c,a4vzm4j285sppw.6d5kzmgt51y1qxm5zun7d7y1mwdiy7xw0v.hgy4nq9fafkdt9dx7.1a8m,tpsedtv6hmzdmwu2r0d9ygox3g,ut9rs1
